Algonquin wolves -origin different than we thought?

The Algonquin wolf, also known as the Eastern wolf is a species which has been discovered in the eastern USA and Canada (click on the bold name above, to visit the species page). 

Perhaps, understandably, it is hard to find a new species in the USA unless it is already pretty rare. This species is only thought to have around 500 individuals, throughout its range (eastern USA and north into Canada).

South-eastern Canada has been known for a race of wolves and coyotes, that do not appear quite right for some time. This study suggested that this group of wolves split from the rest of wolves around 67,000 years ago. This appears to recent to give rise to the significant genetic differences, but it appears that this population also bred with coyotes around 37,000 years ago, and has continued to have genetic exchange between both species (on occasion) since.

As such, it is suggested that the Eastern wolf largely owes its appearance to hybridization between all three.

Has this lead to a more successful species? Well, one may well suggest not, given the small number of these wolves that survive at this time.

However, this is a well settled part of North America, suggesting that in fact it could be down to human hunting rather than natural forces.

Amazon River Dolphin

Amazon Dolphin

The Amazon river dolphin, (other names include boto, bufeo or pink river dolphin), is a species of toothed whale endemic to South America and is classified in the family Iniidae. Three subspecies are currently recognized: Amazon river dolphin,, Bolivian river dolphin and the Orinoco river dolphin while position of Araguaian river dolphin  within the clade is still unclear The three subspecies are each found in a separate river basin (in order) the Amazon basin, the upper Madeira River in Bolivia, and the Orinoco basin.

The Amazon river dolphin is the largest species of river dolphin, with adult males reaching 185 kilograms (408 lb) in weight, and 2.5 metres (8.2 ft) in length. Adults acquire a pink colour, more prominent in males, giving it its nickname “pink river dolphin”. Sexual dimorphism is very evident, with males measuring 16% longer and weighing 55% more than females.

Like other toothed whales, they have a melon, an organ that is used for bio sonar. The dorsal fin, although short in height, is regarded as long, and the pectoral fins are also large. The fin size, unfused vertebrae, and its relative size allow for improved manoeuvrability when navigating flooded forests and capturing prey.

They have one of the widest ranging diets among toothed whales, and feed on up to 53 different species of fish, such as croakers, catfish, tetras and piranhas. They also consume other animals such as river turtles, aquatic frogs, and freshwater crabs. However, this is not particularly surprising, as there are so many forms of life in the Amazon rainforest, and plenty is likely to occasionally find themselves in the river.

In 2018, this species was classed as endangered, by the IUCN with a declining population. Threats include incidental catch in fishing lines, direct hunting for use as fish bait or predator control, damming, and pollution; as with many species, habitat loss and continued human development is becoming a greater threat.

While it is the only species of river dolphin kept in captivity, almost exclusively in Venezuela and Europe, it is difficult to train and often die very young, when kept in captivity..

Life expectancy of the Amazon river dolphin in the wild is unknown, but in captivity, the longevity of healthy individuals has been recorded at between 10 and 30 years. However, a 1986 study of the average longevity of this species in captivity in the United States is only 33 months. An individual named Baby at the  Duisburg Zoo, Germany, lived at least 46 years, spending 45 years, 9 months at the zoo.

Below you will find any news articles on Amazon dolphin (though articles with both words also get sucked in). Also  we will add any information on where you can go to see these in the wild, beneath both of these.

North Pacific right whale

North Pacific right whale

The North Pacific right whale is in a similar position. In the eastern North Pacific there is a population of 30-35, while the western North Pacific is around 300.

It should be noted, that despite this numbers, the North Pacifi right whale is only considered Endangered. not critically endnagered.

While hunting was the initial driver to drop the population. Current threats include ship strikes, as well as entanglement in fishing gear, and of course the small size of the population. Some of the places with the highest density are Bering Sea, Gulf of Alaska, Okhotsk Sea, Kuril Islands, and Kamchatka area, though I should mention that this is a huge area, so does not help a great deal.

Below is a video of a rare sighting of this species. Below that is a list of references to this species on this website (if any). Below this, we will add any opportunities to see this species in the wild.

Beluga Whale

Beluga Whale

Beluga whales are only found in the arctic and sub-arctic oceans. They are one of just 2 species in their family Monodontidae, and are unique in their genus of Delphinapterus. It is also known as the white whale, the sea canary and the Melon-head (though the melon-headed dolphin is a species of its own, so this name may cause some confusion.

Adaptions it has for the Arctic, include the fact that it is white in colour, allowing it to blend into the white world more effectively, and the fact it has no dorsal fin, which allows it to swim very close to the ice sheet above.

Growing up to 5.5m in length and up to 1600kg they are a pretty large dolphin. Generally, living in groups of around 10, in the summer, they group together in their hundreds or thousands.

The worlds population is thought to be around 200,000, Some populations move from the edge of the ice cap, into rivers in warmer areas, while others stay around the ice caps year round. Groups of people in both USA and Russia have hunted them for many centuries.

Hunting is not controlled, and as such the drop in population could happen quite fast. Russia and Greenland have killed enough to drop their local population significantly, though thankfully not Alaska or Canada.

They do also have their natural predators in both the killer whale and the Polar bear.

They are the most commonly kept cetaceans in the world, with around 300 in captivity. Japan, USA, Ukraine, Canada, China and Russia as well as a few more.

There are 22 populations around the world, these vary from 39,000 down to as little as 500. The total population is around 200,000. While this number is large, the number hunted is definitely not sustainable. There is also no care to distinguish the different populations, which suggests that sub-populations could be pushed to extinction without any care.

Below, you will find a clip from a bbc documentary which features this species. Below this, is a list of any mentions that the beluga whale has had on this site. Below this, I will list any opportunities to see this species in the wild. Click on list your wild place, to list yours.

Humpback whale

Humpback whale

The humpback whale is a widely recognized species. Weighing around 40 tonnes, and measuring 14-17m. It is known for its habit of breaching (as above) which can be heard from miles away, and its incredibly complex song, which can last between 4 minutes and 33.

Their low sounds can be heard by whales 1000 miles away, and have been picked up by electronic sources far further away than that.

Whaling did horrific damage to this species, with their population falling to just 5000 in the 1960s. Thankfully, having been protected, the population is now around 135,000. Subspecies are more varied, with those in the northern hemisphere less secure. The least secure is the Arabian sea population, which is thought to be isolated for 70,000 years and there are only 80 that remain.

Threats to individual whales include entanglement in fishing gear, ocean noise and collisions with ships.

They are known to have hunting methods more complex than most baleen whales, including bubble netting which forces the fish into tighter shoals to then be taken in one mouthful.

Young are predated by orca in some parts of the world, and many carry scars from these encounters to the end of their lives.

 

Blue Whale

Blue whale

Abundant in almost all of the worlds oceans until the 19th century, they were hunted close to extinction. In 1966 hunting of them were banned.

There are places around the world, where these animals can be watched, we hope to link to many of these below.

At their peak, before whaling, it was thought that their was around 350,000 in the world. Now there is between 10,000 and 25,000 around the world.

It is certainly not the time to allow them to be hunted again, far from it.

One recent suggestion, is that whales sink huge quantities of carbon down into the ocean, and that our current problems with global warming might have been tiny if we had not killed the vast majority of most species of Baleen whales.

Below is a small outtake from blue planet, the bbc series from 2001 which features a blue whale in the vastness of the ocean

I have included a second video clip, as this one give you an idea of the size and shape of a blue whale, in a way that little footage does.

Below this is any articles that have been written about blue whales on this website, and below that, we will add any links that might help you see blue whales in the wild.

Bowhead whale

Bowhead whale

Also known as Greenland right whale, Arctic whale, steeple-top, and polar whale, they are closely related to the right whales, the bowhead whale looks quite different. It is in a different genus to the other right whales (so is a more distant relation.

The only whale that is endemic to the Arctic and sub-arctic, its mouth is a third of the size of the body. They are incredible long lived often living to 200 years old. They have incredibly thick skulls, which allows them to use their heads to break through the arctic ice.

Unfortunately, they were an early target of whalers, and so in 1966 hunting of them was banned. They have recovered to the point where out of the 5 subpopulations, 3 are endangered, one is vulnerable and the last one currently classed as low risk. Another unfortunate effect of whaling, was to put an end to the summer habits of the bowhead whale – before whaling, it appears that different whale populations would cross seas during the summer, and interbreed.

  1. The Western Arctic stock in the Bering, Chukchi, and Beaufort Seas estimated at 12,500 (though with 95% confidence range 8000-19500         
  2. The Hudson Bay and Foxe Basin stock estimated at 345 with a high confidence
  3. the Baffin Bay and Davis Strait stock which is estimated at over 1000 individuals
  4. the Sea of Okhotsk stock contains only 100-200
  5.  The Svalbard-Barents Sea stock was hunted to near extinction. As such while I cannot find a number, it is unlikely to have a large population

Southern right whale

Southern right whale

The Southern right whale, like the other species in its genus, was hunted incredibly close to extinction. As a wide ranging species, when the population fell possibly as low as 300 in 1920 – so this species was saved by its low numbers, not the ban on hunting in 1935, which likely would have come too late.

It should be noted that Russia ignored this role until 1970. During these 35 years, many were killed by Russia, and when I say many, we are talking hundreds of thousands of species that everyone else was trying to save.

The population is now thought to be around 13,600, which is an impressive increase in around 100 years, of around 45 times increase. The historical population is estimated to lie between 55,000 and 70,000.

So where can they be watched? Far and away, the best known place to see them is Hermanus in South Africa, where around 100 whales congregate each year. I have seen them here, and it is a relatively easy species to see if you are in the right place. They are found from around around 20 degrees South to 65 degrees South around the world. In the past New Zealand was a fantastic place to watch them, and in recent years they returned for the first time in 80 years. They are also naturally seen in big numbers around Australia, and places like Patagonia.

African Dwarf crocodile

African dwarf crocodile

The dwarf crocodile (also known as the African dwarf crocodile, broad-snouted crocodile -a name more often used for the Asian mugger crocodile) or bony crocodile), is an African crocodile that is also the smallest living species of crocodile.

Found in lowlands to mid-height areas, in small and mid-size streams (they avoid large rivers). Generally, they live in rivers that lie in rainforest, though they will venture into the open.

They are known, in places, to be found in pools deeply isolated in Savannah. In western Gabon, there are also a group which have been living long-term in caves. It is considered vulnerable by the IUCN and is Appendix i of CITES. Where they are declining, it appears largely as a result of deforestation and hunting for the bushmeat trade. As a result, while in some regions they have a healthy population, in others (like Gambia and Liberia) they are almost lost.

In zoos in the USA and Europe there are a few of this species, however, records are not good, and quite a few of them are clearly hybrids with little conservation use. I should note, a zoo I occasionally volunteer at (marwell zoo) had one of these crocodiles until last year when it went to another zoo for breeding.

We hope to be able to list places for you to visit to see this species as soon as possible. Any of these will appear below the video and the news section (this lists all the times that this species has been mentioned (if any) in this blog). Below this, we will list all the easiest places we have connections to, to see this species.

 

African Nile Crocodile

Nile crocodile

The Nile crocodile is spread widely throughout sub-saharan africa (except for parts

 of South Africa, thought to be natural and not due to hunting). A suggested subspecies is found in western Madagascar, there are 7 such subspecies, though none have been officially recognized.

While it was originally thought to be the same species as the western African crocodile (confusing given its range), it has actually been found to be closer related to various crocodiles from the Americas, particularly the American crocodile. As such, parts of the map above may actually host west African crocodiles exclusively.

The Nile crocodile is considered the second largest on earth, only beaten by the saltwater crocodile of Asia, interestingly, interestingly the saltwater crocodile is also the only crocodilian that has a greater range than the African crocodile. It was thought that the crocodile had arrived on Madagascar in the last 2000 years – after the extinction of the endemic Voey crocodile, but recently a skull was found and dated to be 7500 years old, suggesting that they must have coexisted for millennia.

While rarely venturing into the sea, they can (like all true crocodiles) survive here, and one was found alive 11 miles off the South African coast in the past.

They have been found in the Florida Everglades, presumably after an illegal introduction – there is so far no evidence of them successfully breeding here. It is unclear of their origin or where they came from, though they are genetically most similar to crocs from South Africa.

While they usually only dive for a few minutes at a time, they are capable of holding their breath for 30 minutes of activity under water – impressively, those inactive under water can stay down for around 2 hours. While rapid and effective hunters in the waters and along its edge, they are far less capable away from the water, and it is rare that they hunt away from water, having said this they are known to hunt here, and are incredibly adaptable to any opportunity. They have a surprisingly small stomach, only the size of a basketball.

Only around 10% of eggs will hatch and around 1% will survive to adulthood. Certainly, much of this damage is down to the Nile monitor lizard, which is thought to be responsible for as much as 50% of the eggs on its own, though median sized cats, baboon troops and mongooses all attack crocodile nests with regularity. Once born, crocodiles are even more at risk, both from animals already mentioned, as well as virtually every predatory water bird, from storks and egrets to even pelicans. Unfortunately, the biggest threat are other adult crocodiles which will happily eat young. While the mother does stay around, and aggressively protects her young, there are so many animals trying to snag a meal, many of the young crocodiles are caught during this time.

The biggest threats include loss of habitat, pollution, hunting, and human activities such as accidental entanglement in fishing nets.

Current estimates are around 250,000 to 500,000. In some parts of Africa they are farmed for their hide (their meat is unpleasant).

Their population is less healthy in western and central Africa, being more sparsely spread. This also makes it hard to do an accurate assessment of their status in this part of Africa.

Along with the saltwater crocodile, the African nile crocodile is estimated to kill anywhere from hundreds to thousands of people each year, with attacks generally carried out by larger crocodiles (thought to be over 3.5m). Given the numbers, it is thought that nile crocodiles and saltwater crocodiles are the most successful hunter of humans – far more fatalities than great while sharks. One study suggested, that while the danger of lions was well known, there was a bizarre feeling that crocodiles were not dangerous. The numbers may well be down to the fact that crocodiles live in water – a place where humans are forced to go regularly.

Below this is a list of any articles released on this site, which mentions the Nile crocodile. Below this, is a video of the species, and below this, we will add links of places to see this species, though if you visit wild places, all savannahs listed on the site will have nile crocodiles.
