The sea otter (Enhydra lutris) is a marine mammal native to the coasts of the northern and eastern North Pacific Ocean. 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. Although it can walk on land, the sea otter lives mostly in the ocean.

A dead green sea turtle is collected from the beach at the Khor Kalba Conservation Reserve, in the city of Kalba, on the east coast of the United Arab Emirates, Tuesday, February 1, 2022. A staggering 75% of all dead green turtles and 57% of all loggerhead turtles in Sharjah had eaten marine debris, including plastic bags, bottle caps, rope and fishing nets, a new study published in the Marine Pollution Bulletin. The study seeks to document the damage and danger of the throwaway plastic that has surged in use around the world and in the UAE, along with other marine debris. (Photo by Kamran Jebreili/AP Photo)
