After diving down to find their food, sea otters hold the shells against their stomachs as they break them open with rocks or other tools.
An adult sea otter's coat can contain up to one billion individual hairs!
A raft of sea otters can number anywhere from 10 to 100 otters.
Sea otters' lungs are two-and-a-half times bigger than a similarly-sized land mammal, which gives them the buoyancy needed to float on their backs.
