Agile Mangabey

Agile Mangabey

The agile mangabey is an Old World monkey of the white-eyelid mangabey group found in swampy forests of Central Africa in Equatorial Guinea, Cameroon, Gabon, Central African Republic, Republic of Congo, and DR Congo.

Until 1978, it was considered a subspecies of the Tana River mangabey. More recently, the golden-bellied mangabey  has been considered a separate species instead of a subspecies of the agile mangabey.

Similar to other mangabeys, they are active during the day. Although generally tree-living, they do spend a significant portion of their time (12–22%) on the ground, especially during the dry season. It is often heard first, and males have a loud, species-specific call that is believed to be used to space themselves out – in a similar way that wolves operate with howls. Other calls are also used to maintain group cohesion and warn of predators. Group size can be as high as 18 members, led by a single dominant male. Group meetings can be friendly and may involve exchange of members.

Adult males not in groups often travel singly.

Fruit makes up a major portion of the agile mangabey diet. They are known to eat at least 42 different species of fruit. Their tooth structure and powerful jaws allows them to open tough pods and fruits that many other monkeys can not access. Agile mangabeys eat from a number of dominant swamp-forest trees, including Irvingia, Sugar plums when they are fruiting. They also eat fresh leaf shoots from Raffia palm when fruits are scarce. Grass and mushrooms, Invertebrates, bird’s eggs and some vertebrate prey, such as rodents.

As we find links, to help you book to see this species, the links will be added at the bottom of the page.

The primates are in some ways one of the most successful families. It is true that many are now endangered, however, unfortunately, that is as a result of the run-away success of the most successful member of the primate family us! Having left the rainforests behind, we have been reducing their coverage dramatically over the last few centuries. 

The sad thing, is that while we have pushed many of our closest cousins towards extinction, the loss of forests may well cost us dearly in the future as well. As a species, we need to pull together to meet this challenge. in order to jump to the various families, click on the family of interest above – though all can also be reached by scrolling down.

Great Apes

Chimpanzee
Boonobo
Sumatran Orangutan
Borneon Orangutan
Tapunali Orangutan
Humans on the beach
Eastern Lowland gorilla
Mountain Gorilla
Western lowland gorilla
Cross river gorilla

Great ape Family split is thought to have split from its nearest relative – the gibbon family, around 17 million years ago.

4 million years later the Orangutan family split from the gorilla line and the human/chimp line.

3 million years after this (so around 10 million years ago) the gorilla family split from the Homo (humans) and Pan

Finally the human line (homo) split from the Pan line 5-6 million years ago.

It should be noted, that chimpanzees and Bonobos split from a common ancestor just 1.8 million years ago. This occurred as the two populations ceased to be able to have contact with each other – the Congo rive formed between 1.5 and 2 million years ago.

For more information on each species, click on their photo and this will take you to their page

It should be noted that while I have grouped eastern western and skywalker gibbon together, there is some contention that the skywalker gibbon should be in its own genus, having diverged around half a million years aog

Gibbons

siamang gibbon genus Symphalangus
hookock gibbon (Eastern, Western and Skywalker) Genus Hoolock
genus Normascus (crested gibbon)
Genus Hylobates (dward gibbons) Agile gibbon

Genus Nomascus

This family is the Genus: Nomascus or crested gibbon.

The last Genus of gibbons is Hylobates: dwarf gibbons.

Whales, Dolphins and Porpoises family tree

Cetaceans -Whales, porpoise and dolphins

Few people can avoid stopping to watch, if they spot cetaceans from a cliff. While the family is wide and varied, they are all pretty interesting. From some of the largest and most intelligent hunters such as killer whales to the largest animal on earth the blue whale.

Whale and dolphin watching tourism is worth a lot of money – this can be essential, as in many places the extra money helps a community survive. 

I hope, overtime, to make this section of the website as large a list of places to view cetaceans and people who will help you in that quest.

As might perhaps be suspected, all of the mammal species which have returned permanently to the sea, and developed breathing holes located on their back (and therefore perfectly placed for taking quick breaths) are  related.

So what is the most closely related living land mammal? Perhaps obviously, it is a species which spends much time in the water – the hippopotamus.

As with all of these pages, as we create pages for each individual species, they will be linked to the photo below.

So the baleen whales are split into three families, these are not large as there are only 16 species of baleen whales in the world. At the current time, there are roughly 1.1 million baleen whales in the worlds oceans

Below is a family tree of the group

 

Baleen Whales

Baleenideae – the rhight whales

 

The first  living split is Baleenidae, this family is not huge. The north atlantic and north pacific are closest related, these species are closely related to the Southern pacific right whales. Their name is unfortunate – it is called right whale for 3 reasons, it swims slowly, floats when dead and carries a large amount of oil. This lead to all these species being hunted close to extinction.

North Atlantic right whale
North pacific right whale
Southern right whale
Bowhead whale

The other family is called Balaenopteroidea. Here species peel off slowly. I will list them in the order that they split.

The first split is the minke whale – of which there are 2 species, the common and southern minke whale, with the grey whale being the next most similar.

The next are the humpback whale and the fin whale followed by the Blue whale.

This completes the list of baleen whales. The other branch of the Cetaceans is known as the toothed whales

Toothed Whale

.I am going to look at them in 3 groups, though the third is not particularly closely related to each other

  • Delphinoidea: This includes
    • Monodontidaes – Belugas and narwhals
    • Phocoenidae – The family of Porpoises (7 species) such as harbour porpoises and Vanquita

    • Delphininidae – these are the oceanic dolphins – 37 species split into several subfamilies which we will deal with one by one.
Subfamily Delphininae – 15 species (tamanend bottle nose dolphin only recognized as separate species, will build page for it at some point when photos are readily available.

Subfamily  Globcephalinae 11 species

  • Inioidea : This includes 3 groups
    • Iniidae (only 1 of 5 genus remains -Inea (4 species: Araguaian river dolphin, Bolivian river dolphin  and Orinoco dolphin)
Amazon river dolphin by Oceancetaceen sometimes known as the Orinoco
Araguaian river dolphin by Rio Cicica
Bolivian river dolphin by Ramon and Suzanne Vargas
    • Lipotidae: which contains only one species: the Baiji or Chinese river dolphin
  • Pontoporiidae: which contains one species 
La plata dolpin

The next family is the beaked whales. There are 24 species, of which only 3-4 have been well studied. This is because they spend much of their time deep in the sea, it appears that each species does not have many members and they are incredibly reclusive in their habits.

One might ask how an air breathing animal can spend so much of its time deep in the ocean? Well the Curved beaked whale has had a dive timed at 138 minutes. More incredible, they only need around 2 minutes to catch their breathe before sinking back into the depths. This means that if required, they can spend just 20 minutes out of 24 hours at the surface – an incredible stunt.

There appear to be a great number of species that are extinct – these we will not list, but will mention each subfamily in passing.

Incertae sedis contains 5 extinct genus, Basal forms include 13 extinct genus

Subfamily Berardiinae contains 3 genus, 2 of which are extinct, but the third contains 3 living species (and one dead) .  

Genus Beradius

 

Arnoux's beaked whale
Baird beaked whale
Sato beaked whale

northern bottlenose whale
Southern bottlenose whale
Tropical bottlenose whale

Subfamily Ziphiinae  contains 5 genus, 3 are extinct, but two have just one species in each

Genus Tasmacetus: Shepherds beaked whale Genus Ziphius: Cuviers beaked whale

The most populous genus Mesoplodon – mesoplodont whales

As you can see, many of the pictures are of dead whales, or skulls or diagrams, or even just text. This is because sightings of many species are so rare that they have never had a photo taken

As you can see from the whale family tree, the sperm whales are separate from the rest. However, they are toothed whales so belong in this section of the page.

Golden Jackal

European golden jackal

Golden Jackal

The Golden jackal is a species found across the south eastern part of Europe as well as throughout much of southern Asia. It is the animal which the African wolf was confused with, and the reason that it was described as a species so recently.

 

Despite its name, the Golden jackal is not closely related to the African Black-backed jackal or Side-striped jackal, which are part of the genus Lupulella, being instead closer to wolves and coyotes. The ancestor of the Golden jackal is believed to be the extinct Arno river dog that lived in southern Europe 1.9 million years ago. It is described as having been a small, jackal-like canine. Genetic studies indicate that the Golden jackal expanded from India around 20,000 years ago, towards the end of the last Last Glacial Maximum. The oldest Golden jackal fossil, found at the Ksar Akil rock shelter near Beirut, Lebanon, is 7,600 years old. The oldest golden jackal fossils in Europe were found in Greece and are 7,000 years old.

Golden jackals live eight to nine years in the wild and up to 16 in captivity.

Living nearby human settlements, Golden jackals are strictly nocturnal. However, those living in other areas can be partly diurnal. They generally live in pairs or as a family unit. Living in pairs, the jackals share most of their activity with their partners. By hunting together they are three times more successful, than hunting alone. Jackal families hunt on a territory of about 2-3 sq. km. all year round. Looking for shelter, they frequently use caverns, dug by other animals. Golden jackals can also dig caverns themselves as well as use crevices in rocks. They are very friendly to their partners. Scratching one another all over their bodies is a common activity between mates. Nevertheless, once strange jackals encounter each other, their behaviour shows subordination, domination, and even readiness to attack.

Niokolo-Koba national park, Senegal

River Gambia Niokolokoba National Park Credit: United states Government

A fascination reserve with a wide range of wildlife, this is a place well worth a visit. With a variety of habitats, the range of wildlife that can be seen is not usually available in one reserve anywhere else.

 The national park is known for its wildlife. The government of Senegal estimates the park contains 20 species of amphibians, 60 species of fish, 38 species of reptiles (of which four are tortoises). There are some 80 mammal species. These included (as of 2005) an estimated 11000 buffaloes, 6000 hippopotamuses, 400 western giant eland, 50 elephants, 120 lions, 150 chimpanzees (It is inhabited by a banded forest in the park (Lower Rim) and Mount Assirik. (north-western limit line where chimps are distributed.)), 3000 waterbuck (Kobus ellipsiprymnus), 2000 common duiker (Sylvicapra grimmia), an unknown number of red colobus (Colobus badius rufomitratus) and a few rare African leopards and West African wild dogs (Lycaon pictus manguensis), although this canid was thought to be wiped out throughout the rest of the country.[4]

 

Other mammals include roan antelope, Guinea baboon, green monkey, patas monkey, warthog.

 

Around 330 species of birds have been sighted in the park, notably the Arabian bustard, black crowned crane, Abyssinian ground hornbill (Bucorvus abyssinicus), martial eagle, bateleur (Terathopius ecaudatus), and white-faced duck (Dendrocygna viduata).

 

There are also reptiles such as three species of crocodiles, four species of tortoises

 

aaa Victoria falls national park, part of the KAZA transfrontier park

Victoria Falls national park, Zimbabwe, Part of KAZA transfrontier park

One of natures greatest spectacles, the Victoria falls lie within the national park that takes its name, and in turn is part of the vast Kalahari Zambezi Transfrontier park. The area around the falls contains a wealth of wildlife, Covering a total area of 56 000 hectares, both parks lie on the southern bank of the Zambezi River which forms the border between Zimbabwe and Zambia. There are a number of picnic and fishing sites available. Activities include guided tours, walks, day and sunset cruises, game drives and adventure activities.

The Rainforest – Here visitors can see unique flora and fauna. Bird species and small mammals may be spotted beneath the forest canopy whilst following the paths through the groves of Date Palm, Fig and Mahogany.

The Game Park – Elephant, Lion, Buffalo, Leopard and White Rhino (the Big Five) can be seen in the park as well as herds of Eland, Sable Antelope, Zebra, Giraffe, Waterbuck and Kudu amongst other smaller species. The Zambezi River is known for its Bream and Tiger Fishing. There are two game drive routes, one accessed through the main gate and the other from just outside town on the Bulawayo road.

aaa Semuc Champey, Guatemala

Semuc Champey, Guatemala

A small reserve in Guatemala, lying deep in the forest, this place consists of a natural 300m limestone bridge. The Cahabon river passes under this bridge, whille above there are a series of stepped turquoise pools which visitors can swim in.

However, this is merely a tranquil place to pause, and lies deep in the rainforest

As this image shows the area is still largely forested, Semuc Champey lies in the middle of the screen

A variety of wildlife frequents the site and the surrounding rainforest. Varying from a wide range of bright birds such as toucans and humming birds, to howler monkeys which are often around the entrance to the site.

aaa Sea of Cortez

Sea of Cortez, gulf of California, USA

With the Colorado river in the north to the Baja peninsula in the south, the sea of Cortez is relatively large and is scattered with around 240 islands.  While there is some wildlife to be explored on some of the islands, the seas are also teeming with a wide variety of species. On the surface blue fin humpback and sperm whales can be seen, alongside bottlenose dolphins Guadeloupe fur seals and leaping Mobula rays. There are also a wide variety of sea birds. As well as all this that can be seen from a boat, there is also a large number of coral reefs, meaning it is hugely popular with snorkellers and divers as well.

aaa The black forest, Germany

The black forest, Germany

This is a large forested mountain range in southwest Germany boarded by the Rhine valley to the west and close to the borders with France and Switzerland. Both the source of the Danube and Nekar river is in this mountain range. With a length of around 100 miles at an area of over 2,300 square miles it is a significant patch of wilderness.


With wolves just returning to the country, their migration into the black forest is only just beginning. Indeed, while in recent years it was known that there were a couple of lone males in the reserve, a lone female has recently been seen – suggesting that it is highly likely young wolf cubs will arrive in the next few years. Other than the wolves there are boar, lynx, otters, foxes, red and roe deer and a variety of other animals.

aaa Pureto princesa subterranean river national park

Pureto princesa subterranean river national park, Philipenes

Located in the St Paul mountain range on the west coast of the island of Palawan, the park contains the Puerto princesa subterranean river. 165 species of bird have been recorded in the park including the blue naped parrot and this Tabon scrub-fowl. There are also a total of 30 mammal species recorded, the long-tailed macaque is most often seen in the forest canopy or looking for food along the sea shore at low tide. Other mammals include the Palawan bearded pig, the Palawan stink badger and the Palawan porcupine. There are also a list of 19 reptiles which include the common reticulated python, the monitor lizard, and the green crested lizard.
