It lives in a giant kelp bed near San Clemente Island, California (background). Scientific studies indicate that the otters act as a keystone species in a kelp forest system by helping to control the populations of sea urchins and other kelp-eating species.. avoiding direct competition.. encouraging mutualistic interactions.. enabling prey to hide from predators.. creating new resources.. allowing abiotic factors, such as climate or nutrient availability, to influence the community..
