Long-finned Pilot Whale

Long-finned pilot whale

The long-finned pilot whale is not actually a whale at all. Instead it is a large species of oceanic dolphin. It shares the genus Globicephala with the short-finned pilot whale (as you will see on the whale and dolphin page). Long-finned pilot whales are known as such because they have unusually long pectoral fins. Pilot whales get their name from the original belief that there was a “pilot” or lead individual in their groups. The name for the genus, Globicephala is derived from a combination of Latin (“globe”) and Greek kephale (“head”). The specific name is Greek for “black”. This species has also earned the nickname of “pothead whale” in some places because the shape of its head reminded early whalers of black cooking pots.

There is sexual dimorphism in the species. Females grow to a maximum length of up to 6m (20ft), and a maximum weight of up to 2,500kg (5,500lb). Males are significantly larger at up to 7.6 m (25ft) in length, and weigh up to 4,500kg (9,900lb). This makes the long-finned pilot whale the second largest member of the dolphin family, behind the Killer whale (Orcinus Orca).The long-finned pilot whale is top of the list of animals by number of neurons more neocortical neurons than any mammal studied to date, in fact having almost twice as many as humans.

While they can bee seen in groups of several thousand, they are generally an amalgamation of a number of smaller groups. Generally they belong to pods that lie in size from 20-150, with individual family groups of 8-10 adding together to make this group.

 They make a variety of noises, as well as using echolocation in water too murky to use their eyes. In deep dives, the females on either end appear to make the decisions.

They are Considered least concern, with a north atlantic population of around 780,000 though this includes short-finned pilots whales as it is hard to tell them apart.

Below, you will find a video of these animals. Below that, you will find any articles on this subject that have been written or will be. Below that, I will add any links that will allow you to see this species in the wild.

Common Dolphin

Common Dolphin

  • The most abundant cetacean in the world, with around 6 million (it should be noted that there are 1350 humans in the world, for every individual common dolphin).

Despite this fact and its name, the common dolphin is not thought of as the model dolphin (that honour goes to the bottlenose dolphin due to its popular appearances in aquaria and the media). It did, however, feature heavily in Ancient Greek and Roman art and culture, most notably in a mural painted by the Greek Minoan civilization.

It is currently the only member of the genus Delphinus. The common dolphin belongs to the subfamily Delphininae, making this dolphin closely related to the three different species of bottlenose dolphins, humpback dolphins, striped dolphins, spinner dolphins, clymene dolphin, spotted dolphins, fraser’s dolphin and the tucuxi and guiana dolphin.[5] The common dolphin was originally categorized into two different species (now thought to be ecotypes), the short-beaked common dolphin and the long-beaked common dolphin. However, recent evidence has shown that generally long-beaked dolphins of this species have originated from the short-beaked population, and therefore there is no close links between different long-beaked dolphins in any part of the world.

Currently, the common dolphin is divided into four subspecies:

  • D. d. delphis, the nominate subspecies
  • D. d. bairdii, the Eastern North Pacific long-beaked common dolphin
  • D. d. ponticus, the Black Sea common dolphin
  • D. d. tropicalis, the Indo-Pacific common dolphin

A number of fossils were erroneously placed in the same genus, but this has since been corrected. 

Common dolphins can live in aggregations of hundreds or even thousands of dolphins,though are often seen in groups numbering several hundred individuals (with subgroups consisting of 20-30 individuals). Occasionally, different groups will come together to form mega-pods which can consist of over 10,000 dolphins – quite a site to witness. Genetic studies in the Northeast Atlantic suggest that common dolphin pods generally do not consist of close kin, but rather of members that are not closely related. Unlike many delphinids, common dolphins do not live in a matriarchal society. That being said, closely related individuals are usually found in similar geographical locations fairly consistently, providing evidence that this species displays site fidelity (at least in the North-eastern Atlantic). Male common dolphins display greater site fidelity in relation to their kin than females.

Common dolphin pod structure often consists of nursery pods (which includes females and calves), bachelor pods (consisting of all males) and mixed groups of males and females, including sub-adults and calves. Genetic evidence seems to indicate that common dolphins live in fission-fusion societies, where dolphins form pods that are not necessarily stable and do not necessarily consist of related individuals. It is not known if common dolphins form lifelong bonds with other individuals  like the long-term male alliances seen in bottlenose dolphins.

There is some evidence that common dolphins use signature whistles, similar to that of the bottlenose dolphin. These whistles are believed to serve as an acoustic label the dolphin equivalent of a name.  It takes approximately 1 year for a calf to learn its signature whistle after which it remains stable for the rest of a dolphin’s life.

In South Africa, as many as 29 common dolphin signature whistle types were detected. However, it was difficult to determine if each dolphin had its own signature whistle due to the vast number of dolphins present (over 1,000) and anthropogenic background noise. Additionally, considering the vast number of dolphins present and  taking into account their feeding and diving behaviour, it appears that common dolphin signature whistles are also used for group cohesion. Another hypothesis for the function of signature whistles, is that they serve as a beacon for lost individuals.

Common dolphins sometimes associate with other dolphin species, such as pilot whales (note, not actually whales). In the Gulf of Corinth, common dolphins frequently display mixed species association, especially with striped and Rissos’ dolphins. Over one third of all dolphin sightings in the gulf consisted of mixed species associations that partially consisted of common dolphins. In mixed species associations, the ratio of striped to common dolphins ranged from 6-11:1. When Rissos’ dolphins were present (there would usually be only one or two individuals), it appeared that much of their scars were the result of interactions between striped and spinner dolphins. In much of the interactions, the Rissos’ dolphins would chase and herd the common dolphins toward the boat, while the common dolphins would try and swim under the Rissos’ dolphin. When groups of common and striped dolphins would charge at each other, the Rissos’ dolphin would chase the striped dolphins. Sometimes these interactions appeared to be playful, and at other times aggressive. Synchronized swimming and surfacing was commonly observed. These interactions take place in the deepest part of the Gulf, furthest from shore and usually consist of a total of 60 dolphins from all three species.

There have been 15 cases of common dolphin and striped dolphin hybrids being recorded. Genetic and observational evidence has demonstrated that the hybrids are fertile and are capable of not only reproducing with other hybrids, but are capable of reproducing with each of the parent species. Striped dolphins have been known to mate with other dolphins, as the Clymene dolphin is the result of hybrid speciation between striped and spinner dolphins. However, this is unlikely to happen with common dolphins, as their population in the Gulf of Corinth is too low. Common dolphins and bottlenose dolphins have been known to interbreed in captivity. There is one confirmed case of a hybrid between a bottlenose and common dolphin in Southern Spain, an important feeding ground for both species. The mother was a female bottlenose dolphin (dubbed as Billie) who has spent 10 years within a common dolphin pod. Billie was observed assisting common calves reach the surface at three different intervals and would babysit the calves after the mother went through labour. They have also been observed bow riding on baleen whales, and they also bow ride on boats. They are fast swimmers and breaching behaviour and aerial acrobatics are common with this species. They are also known to display altruistic behaviours to support injured members.

The short-beaked common dolphin is pregnant for 10 to 11 months. The new-born calf has a length of 70 to 100 centimetres (2.3 to 3.3 ft) and weighs about 10 kilograms. For the Black Sea population, weaning occurs at between five and six months, but occurs later (up to about 19 months) in other areas. Typical interbirth interval ranges from one year for the Black Sea population to three years for eastern Pacific Ocean populations. Age of sexual maturity also varies by location, but can range between two and seven years for females and three and 12 years for males. No evidence exists of any major reproductive differences between the two species. In captivity, the long-beaked common dolphin has hybridized with the common bottlenose dolphin . One of the hybrids has been bred back to a bottlenose dolphin, demonstrating such hybrids are fertile.

Indo-pacific bottlenose dolphin

Indo-Pacific Bottlenose dolphin

The Indo-Pacific bottlenose dolphin is a species of Bottlenose dolphin. This dolphin grows to 2.6 m long, and weighs up to 230 kg . It lives in the waters around northern Australia , South China, the Red Sea, and the eastern coast of Africa. Its back is dark grey and its underside is lighter grey or nearly white with grey spots. The Indo-Pacific bottlenose dolphin is usually smaller than the Common bottlenose dolphin, has a proportionately longer Rostrum, and has spots on its belly and lower sides. It also has more teeth than the common bottlenose dolphin — 23 to 29 teeth on each side of each jaw compared to 21 to 24 for the common bottlenose dolphin.

Much of the old scientific data in the field combine data about the Indo-Pacific bottlenose dolphin and the common bottlenose dolphin into a single group, making it effectively useless in determining the structural differences between the two species. The IUCN lists the Indo-Pacific bottlenose dolphin as “near threatened” in their Red List of endangered species.

Until 1998, all bottlenose dolphins were considered members of the single species Tursiops truncatus. In that year, the Indo-Pacific bottlenose dolphin was recognized as a separate species. Both species are thought to have split during the mid-Pleistocene, about 1 million years ago. Some evidence shows the Indo-Pacific bottlenose dolphin may actually be more closely related to certain dolphin species in the Delphinus (genus), especially the “Atlantic spotted dolphin”, than it is to the common bottlenose dolphin. However, more recent studies indicate that this is a consequence of reticulate evolution (such as past hybridization between Stenella and ancestral Tursiops and incomplete lineage sorting, and thus support truncatus and T. aduncus belonging to the same genus. Burrunan dolphin T. (aduncus) australis has been alternately considered its own species, a subspecies of T. truncatus, or a subspecies of T. aduncus. Following the results of a 2020 study, the American Society of Mammologists presently classifies it as a subspecies of T. aduncus. The same study delineated 3 distinct lineages within T. aduncus which could each be their own subspecies: an Indian Ocean lineage, an Australasian lineage, and the Burrunan dolphin. The Society for Marine Mammalogy does not recognize the Burrunan dolphin as a distinct species or subspecies, citing the need for further research. Indo-Pacific bottlenose dolphins are very similar to common bottlenose dolphins in appearance. Common bottlenose dolphins have a reasonably strong body, moderate-length beak, and tall, curved dorsal fins; whereas Indo-Pacific bottlenose dolphins have a more slender body build and their beak is longer and more slender. 

Indo-Pacific bottlenose dolphins feed on a wide variety of fish Cephalopod, Squid, researchers looked at the feeding ecology of Indo-Pacific bottlenose dolphins by analysing the stomach contents of ones that got caught in the gillnet fisheries off Zanzibar, Tanzania.  Indo-Pacific bottlenose dolphins live in groups that can number in the hundreds, but groups of five to 15 dolphins are most common. 

In some parts of their range, they spend time with the common bottlenose dolphin and other dolphin species, such as the humpback dolphin. The peak mating and calving seasons are in the spring and summer, although mating and calving occur throughout the year in some regions. Gestation period is about 12 months. Calves are between 0.84 and 1.5 Meters, and weigh between 9 and 21kg. The calves are weaned between 1.5 and 2.0 years, but can remain with their mothers for up to 5 years, some mothers will give birth again, shortly before the 5 years are up. 

In some parts of its range, this dolphin is subject to predation by sharks. 

Its lifespan is more than 40 years. Indo-Pacific bottlenose dolphins located in Shark Bay, Australia, have been observed using sponges as tools in a practice called “sponging”. A dolphin breaks a marine sponge off the sea floor and wears it over its rostrum, apparently to probe substrates for fish, possibly as a tool. Spontaneous ejaculation in an aquatic mammal was recorded in a wild Indo-Pacific bottlenose dolphin near Mikura Island, Japan, in 2012. Indo-Pacific bottlenose dolphins have been observed to swim near and rub themselves against specific types of corals and sponges. A team of scientists followed up on this behaviour and discovered metabolites with antibacterial, antioxidative, and hormonal activities in the corals and sponges, suggesting that they might be used by the dolphins to treat skin infections. its near-shore distribution, though, makes it vulnerable to environmental degradation, direct exploitation, and problems associated with local fisheries. 

The major predators of this species are typically sharks, and may include humans, killer whales, and sting rays. In the early 1980s, many were deliberately killed in a Taiwanese driftnet fishery in the Arafura Sea, off north western Australia. Large-mesh nets set to protect bathers from sharks in South Africa and Australia have also resulted in a substantial number of deaths. Gillnets are also having an impact, and are a problem throughout most of the species’ range.

These small cetaceans are commonly found in captivity, causing conservation concerns, including the effects of removing the animals from their wild populations, survival of cetaceans during capture and transport and while in captivity, and the risks to wild populations and ecosystems of accidentally introducing alien species and spreading epizootic diseases, especially when animals have been transported over long distances and are held in sea pens.

Bottlenose dolphins are the most common captive cetaceans on a global scale. Prior to 1980, more than 1,500 bottlenose dolphins were collected from the United States, Mexico, and the Bahamas, and more than 550 common and 60 Indo-Pacific bottlenose dolphins were brought into captivity in Japan. By the late 1980s, the United States stopped collecting bottlenose dolphins and the number of captive-born animals in North American aquaria has increased from only 6% in 1976 to about 44% in 1996. South Korea, in the 2010s, environmental groups and animal protection groups led a campaign ko:2013 to release southern bottlenose dolphins illegally captured by fishermen and trapped in Jeju Island.

In a study on three populations of Indo-Pacific bottlenose dolphins in Japan, the characteristics of acoustic signals are believed to be affected by the acoustic environments among habitats, and geographical variation in animal acoustic signals can result from differences in acoustic environments; therefore, the characteristics of the ambient noise in the dolphins’ habitats and the whistles produced were compared. Ambient noise was recorded using a hydrophone located 10 m below the surface and whistles were recorded by using an underwater video system. The results showed dolphins produced whistles at varying frequencies with greater modulations when in habitats with less ambient noise, whereas habitats with greater ambient noise seem to cause dolphins to produce whistles of lower frequencies and fewer frequency modulations. Examination of the results suggest communication signals are adaptive and are selected to avoid the masking of signals and the decrease of higher-frequency signals. They concluded ambient noise has the potential to drive the variation in whistles of Indo-Pacific bottlenose dolphin populations.

Small, motorized vessels have increased as a source of anthropogenic noise due to the rise in popularity of wildlife viewing such as whale watching. Another study showed powerboat approaches within 100 m altered the dolphin surface behaviour from traveling to milling, and changed their direction to travel away from the powerboat. When the powerboat left the area and its noise ceased, the dolphins returned to their preceding behaviour in the original direction.

In Shark Bay, Western Australia, on dolphin behavioural responses showed significant changes in the behaviour of targeted dolphins were found when compared with their behaviour before and after approaches by small watercraft. Dolphins in the low-traffic site showed a stronger and longer-lasting response than dolphins in the high-traffic site. These results are believed to show habituation of the dolphins to the vessels in a region of long-term vessel traffic. However, when compared to other studies in the same area, moderated responses, rather, were suggested to be because those individuals sensitive to vessel disturbance left the region before their study began. Although these studies do show statistical significance for the effects of whale-watching boats on behaviour, what these results mean for long-term population viability is not known. The Shark Bay population has been forecast to be relatively stable with little variation in mortality over time. The Indo-Pacific bottlenose dolphin populations of the Arafura and the Timor Sea are listed on Appendix II of the Convention on the Conservation of Migratory Species of Wild Animals “Bonn Convention”. They are listed on Appendix II as they have an unfavourable conservation status or would benefit significantly from international co-operation organised by tailored agreements. The Indo-Pacific bottlenose dolphin is also covered by Memorandum of Understanding for the Conservation of Cetaceans and Their Habitats in the Pacific Islands Region Adelaide Dolphin Sanctuary “Marine protected area”  in the Australian state of South Australia Gulf St Vincent, which was established in 2005 for the protection of a resident population of Indo-Pacific bottlenose dolphins.

When we have links for viewing these species, they will appear below video and the news section

Aardwolf

Aardwolf

The aardwolf is the smallest member of the Hyaenidae family, as you can see from the map, it is a species with two separated populations, one in East Africa and one in Southern Africa. It is insectivorous, and exclusively nocturnal, and is generally thought of as one of the harder animals to see in the wild. If incredibly lucky, you can see them feeding alongside Aardvarks, and even Pangolins, but this is rare.  They favour open dry plains and savannahs.

Looking at first glance rather similar to a thin striped hyena, but with a black mane running from its neck, down its back, it can raise this during a confrontation. 

As it ages, it can loose its teeth, however, due to the softness of most insects, this is not the death sentence that it is in many wild animals.

They will defend a territory from others, that covers 1-4 square km, during the breeding season, but are solitary the rest of the time. Both sexes mark their territory, and they will maintain as many as 10 dens throughout their territory, giving them a nearby bolt-hole should danger approach.

They are careful not to destroy a nest that they raid, and will remember where they are, so that they can return for another meal a few months later.

They generally have a density of 1 per square km at most (though this is far higher than animals like lions.

While some farmers mistakenly kill them, thinking that they threaten their livestock, their diet of insects is often good for the farm animals. Their hide is worth a little.

Below is a video of this species and below this is a list of any articles that mention this species. When we have more contacts, you will find them below the news section.

Clymene Dolphin

Clymene Dolphin

Also known as sort-snouted spinner dolphins, the dolphin is found in the Atlantic. It is the only confirmed case of a species developing from hybrids between 2 species – the Spinner and Striped dolphin.

Looking like spinner dolphins, but with short beak and the dorsal fin is smaller and less erect. They spend most of their lives in waters 100m or deeper. They feed on squid and schooling fish. They are predated by cookie-cuttied sharks.

When they jump, they do spin, though not as often or as much as spinner dolphins.

There are 3 distinct populations – North Atlantic, South Atlantic and Gulf of Mexico, though it is thought that the boundary between Gulf of Mexico and South Atlantic is not firm, as individuals will move between the 2. The Gulf of Mexico population is thought to be roughly 6500.

The West African population is considered appendix ii of cites.

There is a video below. Below this, will be a list of any mentions this species has had on this blog (if any)

Indo-Pacific humpback dolphin

Indo- Pacific humpback dolphin

Found in the eastern Indian and western Pacific oceans, this dolphin inhabits coastal waters in this part of the world. It is also known as the Chinese White dolphin

Coloured grey, pink or white (the pink colour comes from blood vessels near the surface rather than from pigmentation) they have a length of 2m-3.5m in length and a weight of 150kg-230kg. They generally spend their time in groups not larger than 10 individuals.

These are not dolphins who go under for long periods of time, with adults rarely diving for more than 4 minutes. Similar threats to other dolphins, include coastal developments, water pollution, overfishing and an increased number of boats in the water. In 2015 it was classified as vulnerable.

A small population of the dolphins (158) live close to Hong Kong and many have succumbed as a result of toxins ingested from the water.

Because they spend much of their time in shallow water close to the shore, they are more at risk to pollution from things like plastic that can wash into the sea. Plastic also makes it harder or impossible for the dolphins to locate fish with echolocation as a result of the extra things in the body of water. 

Below here is a section which will list every time they have been mentioned on the website. Below that, is a video of these animals. Below that you will find any links (as we make them) which will help you see these animals in the wild.

Panda Bear

Panda Bear

Panda bears are unique amongst the bears, having become a vegetarian species. This means they are of great interest. They also survive only in China, despite the fact that it is the most populace country in the world.

A huge reserve is being created, which should connect most panda populations.

The only bear which has adapted a totally vegetarian diet, Panda bears are well known partly as a result in their face being the mark of the charity WWF, though it’s also likely that China’s panda diplomacy has had something to do with this. Eating almost exclusively bamboo they have a very restricted range in the mountains. Through much effort the current population is 2060 strong. While very expensive and needing high level of fitness, treks to see the Panda can be arranged.

Over time we hope to list many places where you can visit bears and see them in their wild home, these will appear here, and a list of posts we have published on bears will appear below these links

There are 2 subspecies, with the split thought to have occurred around 300,000 years ago.

The standard panda is the one that we all know well. This is the black and white stereotypical panda that we are all familiar with.

These pandas are generally found within Sichuan province in China.

The population of both subspecies of panda is nearly 1900, which means that the population of this subspecies must number between 1600 and 1700. However, as always, we are operating on subspecies so its hard to be sure.

Below, I have included 2 videos of the more common  giant panda.

  • The first is an incredibly rare encounter with a panda bear on one of the roads that crosses their habitat – what a treat for the driver.
  • The second is a mother panda teaching her young how to eat bamboo.
  • The last video shows the training that humans give to pandas. to get them ready for a life in the wild (this is incredibly hard and time-consuming process. While it may be possible to reintroduce captive breed animals , or even a whole population from scratch, it will be far easier if we are able to maintain a minimum wild population instead.

The Qinling panda, is restricted to the Qinling Mountains in Shaanxi at elevations of 1,300–3,000m. These pandas have a brown and white pattern (though largely in the same arrangement.

The population is thought to number 200-300 though numbers are not certain.

Below, I have included 2 videos of the Quinling panda. 

  • The first is a rare piece of footage of a quinling bear on the edge of a local city.
  • The second is footage of possibly the only Quinling bear that is currently found in captivity.
  •  The last video is a more in depth video about this subspecies which has recently be discovered.

Allens swamp monkey

Allens swamp monkey

Given where they choose to live, they are currently listed as least concern, however, the population is declining, as a result of a mixture of hunting for the bushmeat trade, and habitat loss. While it is also hunted by raptors, snakes and bonobos, this hunting relies on the availability of the monkey, which means that as populations decrease there is less hunting, unfortunately we humans have overcome this natural method to stop extinction.

Below is a list of articles on this site which have been published on this site, and below this is a camera trap video of this monkey in the wild. Below both of these, we will add any links to places where this species can be seen in the wild, which will help the survival of this species.

The Manned wolf

Looking, at first glance, like a fox on stilts, it is found in Argentina, Brazil, Bolivia, Peru, and Paraguay, and is almost extinct in Uruguay. It is actually not a wolf or a dog, but instead sits in its own genus Chrysocyon  which means “golden dog”. It is crepuscular and omnivorous, and lives on the open habitat of the South America Savanna. The IUCN classes it as near threatened, while a Brazilian organisation with a similar role lists it as vulnerable.

Its name in a local language calls it a big fox. Indeed some studies have suggested that it should be in the same genus as pseudo-foxes.

A recent study suggested that its nearest relative was the Falkland islands wolf, and its mainland relatives – but you have to go back 7 million years to find a common ancestor with this group.

It only hunts solitarily, and its preferred habitat is grasslands, scrub prairies, and forests.

It is not currently considered endangered, given its wide area in which it inhabits, never-the-less it is recognized as a near threatened species due to its reducing numbers. In Brazil, Argentina and Uruguay it is forbidden to hunt them. It has been used to publicize the fight to protect the Brazilian cerrado, by placing it on one of the Brazilian notes.

This animal was shown in great detail in planet earth 3 episode 3, however, this clip is from a bbc series a few years ago.

As we make contacts which you can use to plan your travel to see this animal for yourself.

Clouded leopard and Sunda clouded leopard

Clouded leopard and sunda clouded leopard

Clouded leopards are actually one of the most ancient cat species, however due to their inability to roar or purr, they cannot officially be considered a big cat (roar) or a small cat (purr) due to their definition, which puts them in an odd category. They are most closely related to snow leopards, and are in the same family as the big cats from genetic research. It has recently been confirmed that there are 2 different clouded leopard species, one on the mainland, and the other on the islands (the sunda clouded leopard.

Both species are considered vulnerable. The mainland clouded leopard is thought to number between 3700 and 5580, while the sunda clouded leopard is thought to number around 4500 3800 in Borneo and 730 on Sumatra.

Clouded leopards are found in the forests of South East Asia. Both Poaching and habitat loss threaten their future survival is not easy to see, it makes it is hard for it to be clear what its current range is. However, if you simply compare extinct to all possible remaining habitat, you can see the best possibiltiy is that range has reduced by around 50%


The clouded leopard has been split into two species – the Clouded leopard found on mainland Asia (big picture at the top), and the Sunda clouded leopard (picture above) found on Borneo and Sumatra (these Sunda Clouded leopards have not interbred for a very long time so are considered 2 subspecies). 

 

This is a further image of a clouded leopard though taken in a US zoo, which allows an easier time of getting a good view of the head.

The map above shows the former and current range for these two species. As we start to link with places on the ground, we are likely to create separate pages for each of these clouded leopard species. Below is a video of each species of clouded leopard.

We look to work with people on the ground. Do get in touch if you live or work in the area, and can help people see these incredible animals click here
