"Our results provide guidance for the conservation of biodiversity in the increasingly fragmented landscapes of the modern world. In the following 30 years, the population of wolves on the island grew to as many as 50, and they were carefully studied. They have four legs to move easily on land, and a long tail to swim through the water. The giant river otter is the longest member of the Mustelidae or weasel family.

"While seals and sea lions have lived in the ocean for 30 million years, and whales and dolphins for more than 50 million years, sea otters have had only about 5 million years to adapt to their marine environment.

Giant Otter This South American otter is the world's largest, at some 6 feet long. In South America, the giant otter resides among hundreds of hungry caimans (a type of crocodilian related to alligators) without any issue. Main Characteristics Giant Otters are the largest mustelid and they are similar to a very large river otter. Here’s why.

They have very soft, insulated underfur, which is protected by an outer layer of long guard hair. Otters have more of a curved form in the water, with most of the body and tail riding just beneath the surface. These genes are present across mammal species, but sea otters seem to have changes in these genes that may have benefitted them during their evolution, the researchers concluded.Beichman, Wayne, Lohmueller and colleagues are currently conducting a follow-up study to sequence the 20,000 genes in 130 other sea otters from populations around the north Pacific Rim, including the Kuril Islands north of Japan, the Aleutian Islands, central Alaska and Baja California, Mexico.The research was funded by the National Science Foundation, the Monterey Bay Aquarium, a National Institutes of Health Training Grant in genomic analysis and interpretation, UCLA's Academic Senate and the UCLA Catalyst Program.The complete list of co-authors may be found in the journal article.Lake Superior island wolves are close to extinctionDespite their low genetic diversity, sea otters are fairly healthy and do not show obvious deformities. It’s a member of the weasel family, and the only marine mammal that doesn’t have blubber to keep it warm.

Sea otters have low genetic diversity, which could endanger their health as a species, a UCLA-led team of life scientists has discovered. It is hoped the material could find diverse applications in contaminant detection, highlighting damage, for example, to packaging, delivering nutrients or therapeutics and even in creating living photographs. Large populations tend to have high genetic diversity (many differences among individuals), while small populations lose much of this diversity, resulting in individuals that are more genetically similar to one another.The sea otter's low level of genetic diversity is similar to endangered species, such as the cheetah and Tasmanian devil, said lead author Annabel Beichman, a UCLA graduate student in ecology and evolutionary biology. Sea otters are the largest mustelid and really robust, plus otters tend to dominate large fish.

In this second standoff between a young female jaguar and a family of otters, the otters prevailed again. Finally, river otters can dive to around 60 feet deep, whereas sea otters, remarkably, can dive to several hundred feet to forage for food. "While low diversity isn't necessarily dangerous by itself, we also found elevated levels of potentially harmful variation within genes, possibly due to a history of population declines -- which could impact the population going forward," Beichman said.
