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.

Atlantic humpback dolphin

Atlantic Humpback Dolphin

The Atlantic humpback dolphin is a dolphin species that is found on the west coastal areas of Africa. Unfortunately the IUCN classes it as critically endangered. Apart from their difference in range with the Indo-Pacific dolphin, they are also different in appearance, particularly colouring. 

It is found along the coast from the Sahara to Angola, generally in water less than 20m deep. It is generally shy, does not ride the bow wave of boats and ariel jumps are pretty rare. Usually found in groups of 1-8, occasionally they have been seen in groups of 20-40.

Generally they look for food in the shallows, and occasionally right in the surf. They have been known to engage in cooperative fishing methods with Mauritanian Imraguen fishermen. They do this by driving the fish towards the shore and into the nets. They favour inshore fish such as mullet.

As in many other parts of the world, and other dolphin species, one of the biggest threats they face is incidental capture in gill nets.

It is considered critically endangered, partly because it has been shown to be damaged by coastal development, and this is increasingly common in its range. We are eager to support its future survival, through any tourism (this helps giving value to the species, and therefore makes sure that local people are invested in its future survival. If you work in tourism of this species, click on the “list your wild place” link on the home page. These links when added, will be added at the bottom of the page. If you work in conservation of this species, do join as a member, we are keen to publish any news that you might have.

Vaquita Porpoise

Vaquita

Found, only in the Gulf of California in Baja California, Mexico. Males grow to 140cm and females grow to 150cm.

It is critically endangered, largely as a result of many getting caught in gillnets which result in bycatch. It is clear that these nets should be banned but it is happening too slow.

Its name comes from Spanish and means little cow. It can clearly be identified from the other porpoises which share its range.

In 2022, it was estimated that just 10 remained in the wild, and unfortunately they continue to be caught by mistake. Unfortunately, the future of this species is not good.

Harbour Porpoise

Harbour Porpoise

This is one of the smallest cetaceans, which spends the majority of its time in estuaries and harbours – though it will sometimes venture up rivers, and have been found 100km from the coast.

They get their name from an anglicized version of the french word Porpois. This in turn comes from a medieval Latin amalgamation of two word – these are porcus (pig) and Piscus (fish). I think that these names are rather unfair, but still.

Its range is the North Atlantic, North Pacific and the Black sea. The populations are not continuous and as such there is a series of sub-populations that are geographically limited.

They are thought to have a global population of around 700,000, the Baltic sea is the only one which is seriously endangered, and that is the Baltic sea population which is thought to be around 500. Others could become endangered if current trends continue such as the Black sea population which is currently estimated to number around 12,000.

They have to spend a great deal of time looking for food, as they need to eat 7-8% of their bodyweight each day.

Generally, they live 8-13 years although individuals have been recorded living to over 20.

Grey whale

Grey whale

The gray whale (other names include grey whale, gray back whale, Pacific gray whale, Korean gray whale, or California gray whale), is a baleen whale that migrates between feeding and breeding grounds yearly. They can reach 14m in length and 41 tonnes. It is found in North pacific – with the Northeast Pacific (American population) and the Northwest Pacific (Asian population) that is endangered. The northern population has been extinct for a long time.

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

Sea-Lions

An encounter with almost any wild animal can be something you remember for years. This sealion that came out of the sea on the beach in New Zealand is no different

Sea-lions

There are 6 living species of sea-lion, and 1 extinct. As the interest in these species grows and the links become unwieldy i will split out the separate species, but for the time being I will just have one page for them all – help it to be necessary to split them as soon as possible. 

Sea-lions are pinnipeds with external ear flaps, long fore-flippers, the ability to walk on all fours, short and thick hair, and a big chest and belly. The sea-lions the 6 living species shown below (the Japanese sea-lion is extinct) in five genera. Their range extends from the subarctic to tropical waters of the global ocean in both the Northern and Southern Hemispheres, with the notable exception of the northern Atlantic Ocean. They have an average lifespan of 20–30 years.[2] A male California sea-lion weighs on average about 300 kg (660 lb) and is about 2.4 m (8 ft) long, while the female sea-lion weighs 100 kg (220 lb) and is 1.8 m (6 ft) long. The largest sea-lions are Steller’s sea-lions, which can weigh 1,000 kg (2,200 lb) and grow to a length of 3.0 m (10 ft). Sea-lions consume large quantities of food at a time and are known to eat about 5–8% of their body weight (about 6.8–15.9 kg (15–35 lb)) at a single feeding. Sea-lions can move around 16 knots (30 km/h; 18 mph) in water and at their fastest they can reach a speed of about 30 knots (56 km/h; 35 mph).[3] Three species, the Australian sea-lion, the Galápagos sea-lion and the New Zealand sea-lion, are listed as endangered.

Steller sea-lion
Australian sea-lion
California sea-lion
Galápagos sea-lion
New Zealand sea-lion
South American sea-lion

Steller Sea-lion are found on the land of North America and Asia that circle the north pole (map below, credit NOAA). 

They are predated by killer whales, though sleeper sharks and great whites sometimes take young. They eat a variety of foods, include various fish species, as well as octopus and squid. They are fast swimmers, capable of diving to 1500feet, and staying under for 16 minutes

During breeding season, males fight to control a stretch of beach, and females move freely to the place they favour. 

Status: population has fallen 70-80% since the 1970s and so are listed as endangered, around 46,000 individuals, though in recent years, the Eastern population has grown at around 3% a year (in 2013 this lead to its removal from the US endangered species list)

 

Australian Sea-lion is the only endemic pinniped found in Australia.

They can make a variety of calls, with mothers and young able to pick up each others call in the chaos of a breeding beach. There are currently 66 recognized breeding beaches, though 42% of pups are bred on just 4 of these beaches.

While rare, a bite can require hospitalisation. In both the 1930s and 1960s they were recorded as feeding on little penguins, and this still happens today. Other food includes a variety of fish and even small sharks, in turn, they are hunted by great white sharks and killer whale (orca).

Population was 14370 in 2010 though by 2014 it had fallen to just 6500 mature individuals, though current estimates are 11,200 suggesting a rebound. Still it is clear that they need particular efforts for their conservation. Despite their (relatively) close ranges, the Australian and New Zealand sea-lions do not appear to be closely related. They are considered vulnerable.

California Sea-lion Are found on the west coast of north America. On this map, the navy blue marks the breeding rance, while the light blue shows the total range that they can be found in. It should be noted, that previously the Japanese and Galapagos sealion were both considered subspecies of the Californian species, but no longer. They can stay healthy, for a time, in fresh water, and have been seen living for a while in Bonneville dam – 150 miles inland.

They see (mostly in blue/green) and hear well, as well as being able to sense nearby, with their whiskers. They generally eat fish, squid and occasionally clams. They have been seen cooperating with other sealions, or indeed dolphins porpoises and sea-birds in their hunting techniques, though exploitation is also common.

There are 5 relatively distinct populations. Several sealions have reached Japanese waters in recent years, and this is the most likely origin, as such  it could return to Japan on its own. 

It is considered least concern with 238,000-241,000 individuals and increasing over time.

Galapagos Sea-lions Found on all of the Galapagos Islands, as well as (in smaller numbers) on Isla de la Plata, which is just 40km from Puerto López a village in Ecuador. There have also been recorded sightings on the Isla del Coco which is 500km southwest of Costa Rica (and 750km from the Galapagos). These are not regular, and so have been considered vagrant. It is of course possible that historically they roamed here, but we cannot say.

They are the smallest species of sea-lion, and can often be seen gliding through the water, or sunbathing on the beach. They measure 1.5m-2.5m and weigh between 50 and 400kg.

Much of their diet is made up of sardines. Interaction with humans is usually negative, and feral dogs often form packs, and can then attack the sealions.

The population tends to bounce between 20,000 and 50,000 and they are currently classed as endangered

 

New Zealand Sea-lion (formerly known as the Hooker sealion) is native to south island, though before 1500 it is thought that it was also found on north island. They tend to breed on Subarctic islands of Auckland and Campbell (99% of the pups are born in these islands). In 1993, sealions started breeding on South Island again for the first time in 150 years.

Genetic evidence suggests that until 1300-1500 there was a mainland subspecies, which was wiped out by the Mauri’s and has been replaced by members from the sub-Antarctic population.

As well as eating fish and crustations, they will take new Zealand fur seals as well. They are hunted by great white sharks, and in a survey 27% of adults had scars from near misses. While south American sealions are hunted by orca (with them famously beaching to catch them) they do not appear to do this around New Zealand. After the birth of their pup, females move inland as much as 2km to avoid males, storms and even parasites.

They are thought to number 12,000 making them the rarest sealion. They are also the most distinct being part of the Genus Phocarctos, and are listed as endangered.

 

South-American Sea-lion

Also known as the Southern sealion or the Patagonian sealion. They have been recorded going as far north as Ecuador, though not yet breeding there. They eat fish, as well as squid and octopus, and have even been observed predating penguins, pelicans and South American fur seals.

Males set up territories, but after the arrival of females switch to protecting them. Having said this, one population in Peru have a different set-up where males perform, and females choose a mate, and are free to move freely. This may be in result to the warmer climate, which means the females make regular trips into the sea.

The total population is estimated at 265,000. They are declining in Patagonia (Argentina) and the Falklands but increasing in Chile and Uruguay. In the 2013 El nino many Peruvian sealions died. They are still regularly killed by fishermen, both for damaging equipment and stealing fish.

They are listed as least concern

 

As we gain contacts each picture above will become a link to a page for the specific species – for now, all species will be looked after by this page. If you are a wildlife guide or live nearby and want to be able to host (as a hotel or B&B or campsite) and would like to be listed do get in touch. Our aim, is to give people all the information and links on one page, so that they can book everything in one go – making it easy, and therefore more people undertaking these sort of trips.

Sea-lions can be specifically searched out, but it is also possible to have a surprise encounter with one.

One of my most memorable encounters with any wildlife, is an encounter with a New Zealand sealion.  We had simply gone for a walk on the beach, and at some point, we saw the sea-lion coming out of the sea. This huge male slowly made its way towards us, and when about 10m away it lay down in the sand, threw sand all over itself and went to sleep.

Ethiopian wolf

The Ethiopian wolf is restricted to the highlands of Ethiopia, and the current count is only 366 ,

Ethiopian wolf

The Ethiopian wolf is a highly endangered canid that is restricted to the highlands of Ethiopia. Other names include the Ethiopian fox, or the Simien wolf.

In terms of size, it is about the same size as the Coyote, Genetically, they are more similar to wolves than all jackals (except the Golden jackal). Here, below you can see how closely related each of the wolves are. While they look rather like jackals, their behaviour is far more like wolves – though due to the prey in the area, they do not hunt in packs (though there are regions of earth where grey wolves do not hunt as a pack either.

Red wolf

Red wolves

Red wolves have varied a bit about whether they should be classed as their own species or a subspecies of the grey wolf, however it has now been settled that they are separate for quite some time.

Size-wise it lies midway between a grey wolf and a coyote. Indeed, despite its serious danger of extinction, it is often missing from the endangered list. It has at various times been suggested to be a cross between the wolf and the coyote, or been a subspecies of the wolf.

It has been listed as critically endangered since 1996 by the IUCN, yet the same species is not listed in the CITES appendices of endangered species.

If or when we write any articles on this subject, they will appear below

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.
