Understanding The Situation
It's very important to contact an experienced marine mammal rescue organization before taking any action. Sea otters belong to the same family as wolverines and, like them, can be very aggressive. They should not be approached by anyone who hasn't been trained handling them.
If you spot a sea otter which you believe is in distress, please contact the Vancouver Aquarium's Marine Mammal Rescue Centre at 604-258-SEAL (7325). If you're outside British Columbia, contact your local animal rescue organization for assistance.
