*** About Sea Otter: Sea otters are a keystone species in the marine environment, known for their ability to significantly influence the ecological balance of the kelp forests. As one of the few mammals to use tools, otters utilize rocks to break open shellfish, their primary food source. Their dense fur is the thickest of any animal, with up to a million hair follicles per square inch, helping them to maintain body heat in cold water. Historically hunted for their fur, sea otters faced near extinction in the past. Conservation efforts have helped to stabilize some populations, but they remain a species of concern subject to numerous environmental threats.:
