they have the thickest coat of all mammals
it is very thick and it keeps them warm. Back in the 1700's over 15,000 sea otters were killed for there coats. And only 50 managed to escape.
sea otters do have hollow fur to help them float... so yes sea otters have hollow hair.
Sea otters are covered in an extremely dense coat of fur, with 1,000,000 strands of hair per square inch (the densest of any animal on earth). Two different kinds of hair make up this coat: short underhair, which retains air and insulates the otter, and long guardhair, which prevent the ocean water from leaking into the underhair. It was because of this luxurious pelt that sea otters were so intensely hunted in the past--which was the primary contribution to today's decimated population of sea otters.

A sea otter lives mainly in coldwater environments. They have no blubber (a layer of fat) which other mammals use to keep themselves warm. Therefore the sea otter has the most dense fur of any mammal. The close placement of the hairs helps to keep the sea otters warm.

But otters use rocks to crack them open and eat them also humans will gut the sea urchin and eat there insidesYou can find out by asking other people like your teacher, parents, friends, and brothers or sisters if you don't think this answer is right. the answer is otters, people, and heron.
