28. What sets the North American River Otter’s vision apart from the many land animals?…
After a long day of swimming the otter would roll on the ground or rub on a log to dry themselves. The Oriental Small Clawed Otter can last up to 6-8 minutes under water, so hunting for food is easy. Their forefeet are helpful because they use them to capture their food and “Their hind feet says wildlife explorer states, “Are used for swimming.” “Their eyes stay shut for 40 days after birth,” states the wildlife explorer. According to the wildlife explorer, “Their number of young is 1-6 but usually 1-2.” One of the most interesting facts is that if several otters are swimming in one straight line with their backs out of the water their backs can be mistaken for the humps of a sea monster. Its genus and species is “Aonyx Cinera” that is also the species for the African Otter. Although they are the same species the African otter is much bigger, and weighs up to 75lb and just like the Oriental Small Clawed Otter and the Asian Otter they all have white markings on their faces, chests and throat. The Oriental Small Clawed Otter is one otter that loves to swim and definitely loves to snack on…
It’s interesting reading so if you’re up for a quick study, see my references below. (Southeast Alaska Indian art linked to adorable pictures of otters above and below, as seen on EsoterX website.)…

My name is Jaron Pierre Jr. and i am going to be talking about the sea otter . The sea otter is a marine mammal native to the coasts of the northern and eastern North Pacific Ocean . They live over 10-15 years . Their breeding season is during September to November , they are territorial during it . Their scientific name is Enhydra lutris . Adult sea otters typically weigh between 14 and 45 kg (31 and 99 lb) , making them the heaviest members of the weasel family , but among the smallest marine mammals . Unlike most marine mammals , the sea otter’s primary form of insulation is an exceptionally thick coat of fur , The densest in the animal kingdom . Even though they can walk on land , the sea otter lives mostly in the ocean . The sea otter…
Some external physical traits between the sea otter, sea mink, and wolverine are short legs and dark, dense, oily fur. The density and oil of the fur helps the animals during the winter, they are easily able to stay warm in the winter or while swimming in the sea otters and minks case and they make them resistant to getting frost on their bodies. These animals also share the fact that they have short tails, small eyes, short ears, placental births, mammary glands, and sweat glands.All these. unshared traits help each species/ organism better prepare and be ready for competition and help the species separately adapt to their ecosystem/ environment at their own…

A keystone species is a species whose presence contributes to the diversity of life in its ecosystem. If a keystone species to an ecosystem were to go extinct, their ecosystem would suffer severally. In the case of the kelp forest the major keystone species is the sea otter. The reason that the sea otter…
Adults grow to about four feet in length and can weigh between 54 and 44 pounds (http://www.otterproject.org/about-sea-otters/biology-of-the-southern-sea-otter/). Sea otters typically live 10 to 12 years. These creatures live mostly on their own. One of the most unique features on the sea otter is its dense fur coat. Most marine mammals have a layer of blubber for warmth, instead the sea otter has one of the densest fur coats in the animal kingdom; they have approximately one million hairs per square inch (http://www.otterproject.org/about-sea-otters/biology-of-the-southern-sea-otter/). The coat has two layers: the first layer is a dense, dry layer and the second is a water-resistant, oily coat to protect the first layer. Grooming their fur regularly is vital to the sea otter’s survival. This dense coat was the reason sea otters were hunted so severely and are currently…
As one of Canada’s most endangered species, the sea otter is in need of public support to aide the government in continuing their efforts of preserving this species in Canada. From the time the vikings first set foot in Canada, the sea otter has had a drastic role in the settling and survival of the European soldiers. Through out the years, it has come to be seen as one of Canada’s most identifiable creatures.…
Orcas, also known as killer whales, have been in captivity for over fifty years. The magnificent stunts the animals are trained to do is jaw dropping. Killer whales, on the other hand, do not seem to feel the same positive regard. Infact, they have killed or injured more than one-hundred people during their stay in captivity. Keeping killer whales in captivity not only threatens the whales, but harms humans as well.…
In the United Kingdom there is an animal fighting to have a comeback into the ecosystem, an animal that has been gone for the past 400 years. This animal is the beaver; the beaver could be just what the United Kingdom needs to help the ecosystem. In England there is a group from the Devon Wildlife Trust (DWT) that is fighting for this comeback of these beaver. The Devon Wildlife Trust understands that these populations of beavers are a keystone species in this ecosystem. Keystone species have the definition of a species that are largely depended on and if removed from the ecosystem change the environment, these beavers being removed from the United Kingdom have made the ecosystem worse. The DWT has many examples to show the whole country to influence their decision.…
The story of the Pacific salmon is a tragic one. Humans have consistently created conditions that threaten the livelihood of the salmon. Yet the salmon continue to fight despite the assault that has taken place on their habitat for over 150 years. In Salmon Without Rivers, Jim Lichatowich (1999) explores this assault as well as discusses man’s attempt to restore salmon to the Pacific Northwest. His detailed analysis of the history of the Pacific salmon sheds light on the plight of the salmon and the response by man to the salmon crisis in the Pacific.…
