Sea Otter: The Original WetsuitHow dense fur inspired a new way to stay warm in water.

Nature Solved It First

Sea otters survive frigid waters not with blubber, but with the world's densest fur. This natural coat traps a layer of air, providing incredible insulation that keeps their skin dry and warm. This evolutionary marvel has caught the attention of engineers. Scientists are now developing synthetic, fur-like materials to create more flexible and efficient wetsuits, inspired by the otter's unique ability to stay warm.
