Sea otters face a number of dangers in the wild including disease from land animals (specifically encephalitis caused by waste from cats and opossums), chemicals threat from runoff (PCBs and tributylin), fishing nets and traps, natural predators like sharks, overactive kelp (red tide), and most of all oil. Oil is the number one threat to the survival of the sea otter.
