How cute is the sea otter! They are a marine mammal which can be found on the coasts of the Northern Pacific Ocean and are the largest member of the weasel family. They have the densest fur in the whole animal kingdom, ranging from 250,000 to one million hairs per square inch. Now that’s a lot of fur!
There are a lot of different interesting sea otter facts, but the most talked about is how sea otters hold hands when they sleep. So, why do they do this?
Sea otters will often float in groups (called rafts) whilst they eat, rest and sleep. A raft of otters can be anything from two otters to hundreds! And, whilst they are rafting, it is well known that they will all hold hands to stay together in their group. Also, the sea otter will use sea plants that grow from the ocean floor which they will wrap themselves up in, which helps keep them from drifting away.
