The Dead Do Tell Tales

With Southern sea otters (Enhydra lutris nereis) being a federal and state-listed threatened species, it is vital to apply expanding knowledge, testing, and analytical techniques to help clarify the dynamic processes influencing their survival. Fifteen years of systematic necropsy, including 560 animals, extensive systematic diagnostic testing, and comprehensive epidemiological analyses were reviewed to investigate Southern sea otter mortality patterns. In this talk, I will discuss the leading causes of death and its relevance to the sea otter population. I will conclude with a discussion about sea otter gastric ulcers and its possible association with Helicobacter enhydrae, which is related to other bacterial species known to cause gastric ulcers in humans and other animals.
