because there fur has blubber in it too keep them warm
so they dont get cold.
Sea otters are adapted to keep warm by its thick and dense fur. It has two layers of fur; one a water proof guard layer, and then a shorter layer of fur underneath. Unlike most marine mammals, they do not use blubber to keep them warm. So they use their fur instead.
so they dont get cold.
They groom there fur because it needs to be clean to keep the otters warm. and it has a pouch under its armpit to hold rocks which they use for cracking shells of animals they eat
Their oily skin keeps them warm in the cold waters.Also they have thick fur to keep warm.
One way is that their fur is really dense to keep the warmth in.
Air trapped in their fur keeps them warm
to keep out the water. the oily fur helps keep warmth in and water out!
Sea otters have incredibly dense fur, to keep it in tip top condition they groom it at every opportunity. This causes air to get trapped between the hair strands, helping to form a barrier to stop very cold water from reaching their skin, which in turn helps to keep them warm.
Because of their specialized fur which is a dense coat that keeps in body heat because they are warm blooded mammals and warm blooded animals take after the temp they live in.
sea otters do have hollow fur to help them float... so yes sea otters have hollow hair.
Oil harms sea otters......if it gets into its fur. The sea otters prey are cats, white sharks, and orcas.
