This study focuses on the community ecology of sea otters and their impact on marine ecology. The need for their inclusion in the Endangered Species list and the implications of such an intervention are also evaluated. Community ecology Sea otters predate on many herbivorous invertebrates, including sea urchins. Sea urchins feed on kelp forests, which are an important habitat for fishes and other marine organisms. A high population of sea urchins has an adverse effect on kelp forests.
