Almost definitely extinct, this species of river dolphin lived in the Yangtze and was also known as the white dolphin among other names.
The last confirmed sighting was now more than 20 years ago, and given the incredibly polluted state of their river home it is unlikely that any did survive. There may well be much debate in the future, as to whether similar river dolphins from elsewhere could replace them. What is clear is that this is irrelevant for a significant length of time, as it is likely to be many decades before the river is capable of supporting significant populations of fish, never-mind a river dolphin.
Below is a rare clip of it from before extinction, and below is any times that it is mentioned on this site. Given that it is extinct, its mentioning may not be helpful for seeing it, but may well be of interest. Below this video, is an automated list of any articles from this site which mentions this species. Unfortunately, as the species is extinct means that the local population cannot benefit from ecotourism, but there are many other species that still cling on in China. All wildlife has the capacity to bring in money for those who live nearby. Help us make this happen
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.Â
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 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
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.

The Rice whale is also known as the Gulf of Mexico whale, is a relatively newly discovered whale. Until 2021, it was thought that this whale was a subpopulation of the Brydes whale, however it is actually genetically distinct.
Growing up to 12.65m and weighing between 13.8-27.2 metric tonnes, it is found in the north-east of the gulf of Mexico. unfortunately it is on the brink of extinction. The deep-water horizon oil spill killed around 20% of the whales of this species.Â
While it has not been observed, the killer whale actively hunts in the area, and has regularly killed sperm whales. Brydes whales have also been targeted, so it seems impossible that rice whales are not targeted.
Around 100 of these whales exist, which is very close to extinction.Â
Whaling caused all sorts of issues. Many whale populations were decimated, and while some have recovered to some degree, few are anywhere near their population before humans started hunting them....

The largest species of whale, the largest species of mammal, indeed at almost 30m the largest species ever known to live on earth, they can weigh up to 200 tonnes. There are 4 subspecies with a possible 5 in contention.
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.
It appears that blue whales have been mating with fin whales far more frequently than previously thought. One of the things that is both exciting and alarming, is that it...

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.
The Western Arctic stock in the Bering, Chukchi, and Beaufort Seas estimated at 12,500 (though with 95% confidence range 8000-19500Â Â Â Â Â
The Hudson Bay and Foxe Basin stock estimated at 345 with a high confidence
the Baffin Bay and Davis Strait stock which is estimated at over 1000 individuals
the Sea of Okhotsk stock contains only 100-200
 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
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.
Despite a desperate attempt to halt this exploration, Shell has started seismic exploration of the ocean floor off the coast of South Africa. Why does this matter? Currently, this sea...
Once thought to exist in numbers between 9000 and 21000, but whaling pushed them close to extinction – with estimates of just a couple of hundred. In the intervening years, since 1986, the population has reached 350 – potentially doubling the population in just 37 years. However, we need to remember that only around 70 of these are breeding age females. A healthy population can expect breeding females to produce a calf every 3 years or so. Unfortunately, given the entanglements and other things that are stressing these whales, the gap between young is currently in the range 6-10 years. This means we can expect 7-11 calves a year – which suggests that for the population to double again in 37 year – we need a survival rate of over 90%
Should the population continue to grow on at that speed, it will take around 180 years for this population to recover.
Places to try to see them include
Jacksonville, Florida
Hilton-head Island
Generally, anywhere along this section of the American coast they are a possibility. Directly below this is a video of this whale species, and below this is a list of any mentions that this whale has had on this website (if any). As we get links, they will appear below these two sections.
The population of the north Atlantic right whales appears to have stabilized at around 350, having fallen from a peak of 483 in just 2010. In 2022 there were 356,...
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.Â
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
Â
Baleen Whales
Baleenideae – the rhight whales
Â
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.
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 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) . Â
Northern                                                           Southern and                            Tropical
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.
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.
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.
