Sleek, furry and streamlined, sea otters are adorable. These marine mammals are custom-built to live in water. In fact, weasels, otters, badgers and skunks ? all of them belong to the family Mustelidae. But among these species, otters are the biggest water rats and the only mammals to have fur instead of blubber! Otters barely come on land and prefer to eat, sleep and even deliver their babies in water! With seal-like flippers and a short tail, they can be seen floating on their backs while eating abalone, their favourite food.

When taking a nap, they tie themselves to seaweeds ? like an anchor ? so that they don?t float away while they are asleep! They are also known to use stones from the ocean floor, to break shells of mussels before gulping them down.
