This study is the first comprehensive genomic analysis of otters. The giant river otter is the longest member of the Mustelidae or weasel family. 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.

Otters usually eat crustaceans, fish, frog, rodents, and the marine invertebrates with hard shells like crab, mussels, etc. The findings have implications for the conservation of rare and endangered species, in which low genetic diversity could increase the odds of extinction.Genetic diversity is a measure of how many differences exist across the genome among individuals in a population. Compare that to giant otters that can grow to 5.9 feet,or sea otters that can weigh up to 100 pounds. The Giant Otter features a very long body, similar to that of a weasel.
