A sea otter wraps itself in kelp
The sea otter is a marine mammal native to the coasts of the northern and eastern North Pacific Ocean. Its many unusual characteristics include the use of rocks as tools to forage and to open shells, luxurious fur that is the densest of all animals with up to 150,000 hairs per cm2 (nearly 1 million per sq in), and its role as a keystone species, controlling populations of marine herbivores which would otherwise inflict extensive damage to kelp forest ecosystems. Although the sea otter belongs to the weasel family and can walk on land, it can also live exclusively in the ocean. Once hunted to the brink of extinction for its fur, the sea otter's numbers have rebounded in about two-thirds of its historic range, a recovery that is considered one of the greatest successes in marine conservation.

Emperor Tamarin

The Emperor Tamarin (Saguinus imperator) is a tamarin native to the Amazon Basin and neighboring parts of South America. It was allegedly named for its similarity to William II, the last German Emperor. The name was first intended as a joke, but has become the official scientific name.
