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.

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.

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

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)

    • 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

Next we cover the Bottlenose whales

Northern                                                                                                                     Southern and                                                        Tropical

brown Bear

Brown bear

With it’s range originally encompassing the whole of Europe, much of Asia, most of North America and the atlas mountains of Africa (the only native African bear), it has unfortunately been in decline for some time. These days the bear habitat consists of Alaska and parts of Canada as well as northern regions of the USA, relict populations in Western Europe though they still have a stronghold in Eastern Europe and and Russia as well as sections of central Asia. Highly intelligent they have never lived at high densities, as members high on the the food chain, few places can support large populations for long. With their impressive intelligence, and inquisitive nature, the can be tough to live alongside. With all that in mind brown bear watching can be an enjoyable pastime in many different places. Around much of the world there are newer hides in places that bears still exist – these allow you to watch bears in their natural habitat. We currently only have one listed (it’s will with a visit, link below) but we are always keen to list many more.

There are many places where bears live happily live alongside humans and are rarely seen.

Over time we hope to list many places where you can visit bears and see them in their wild home. Below this, is a list of any articles that have been written on this species, below that will be links that we have to see bears yourself.

Polar Bear

Polar bear

  • A relatively new species of bear, the polar bear is the only species adapted for polar life. Still being found all around the Arctic, there are roughly 26,000 in the wild at the current time. Whalers and for traders killed many in the 19th century, and while they have recovered experts predict that global warming is likely to lead to the extinction of the polar bear.

Polar bears are distant cousins of the Grizzly bear, and as the weather warms, polar bears are moving south and Grizzlies north. This has on at least one occasion created a so called “Pizzly”. We only know about this, because a hunter who paid to kill a polar bear accidentally shot the Pizzly. I have made it clear my lack of appreciation for the so called hunter – while I am ready to admit that in places the money is useful for conservation, I hope that with your help and this website, we might make it an irrelevance.

Found throughout the arctic, they can be seen in 

  • Alaska (USA) 4000-7000
  • Canada   16,000
  • Greenland 3500-4000
  • Norwegian islands, particularly Svalbard about 3000
  • Russia:22,000-31,000 (note, this adds up to far to many – indeed Russias population alone is above the world population, also some are shared between countries)

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

Lynx (canada)

Canada lynx

The Canada lynx is one of 2 new world species, and is found through much of Canada and Alaska, throughout the Boreal forests of spruce and fir. They are hunted but the harvest is worked out on the basis of the population, so it rises and falls quite a lot. Climate change is effecting its northern range, and unfortunately is bringing this cat and the bobcat into more common contact, leading to an increasing number of hybrids along the area that they meet. There are thought to be 10-12 thousands of the Canada lynx across its range.

Alaskan polar bear refuge at greater threat from oil exploration than thought

Polar bears retreat into dens under the snow in order to have their cubs. Until recently this was an entirely sensible thing to do as these stems would survive very effectively until warm enough for the bear’s to emerge.

polar bear cubs disturb from their dens by oil exploration while too small
