Introduction to Sea Otters
The sea otter (Enhydra lutris) is a marine mammal native to the coasts of the North Pacific Ocean. Known for their playful behavior, these otters are famous for using tools, like rocks, to break open shellfish. They are a key species in their ecosystems, helping to maintain the health of kelp forests by controlling sea urchin populations.
Fun Facts About Sea Otters
- Sea otters have thick fur that helps keep them warm in cold waters.
- They have a favorite rock that they use repeatedly for cracking open shellfish.
- Sea otters are one of the few animals to use tools in the wild.
- They can hold their breath for up to five minutes while diving for food.
Why Are Sea Otters Important?
Sea otters play a vital role in the health of kelp forests, which are crucial marine ecosystems. By preying on sea urchins, otters keep the urchin population in check. Without otters, sea urchins would overgraze on kelp, leading to the collapse of these forests. Kelp forests provide shelter and food for a wide variety of marine species.
