Along the Pacific coast, sea otters help control the sea urchin population. Fewer sea urchins in turn help prevent kelp forests from being overgrazed.
Why sea otters are a keystone species?
Sea otters are a “keystone species” which means that they can exert top-down pressure via predation on sea urchins, which are grazers upon kelp. As urchin density decreases from sea otter predation, so does the grazing pressure on kelp and as a result kelp forests flourish in the presence of sea otters.
Are otters good for the environment?
Otters also have a pivotal role in river ecosystems. They are predators, meaning they help control the populations of food species they prey upon. This affects the ecosystem as a whole, and as a result, their presence is a signal that the ecosystem is healthy.
What are 3 interesting facts about sea otters?
Sea otter fur is the densest of any mammal at about 1 million hairs per square inch (We have 100,000 hairs on our entire head). Wild sea otters typically have a lifespan between 15 and 20 years. Average weight of an adult female California sea otter is about 50 lbs. Males can weigh up to 70 lbs.
