Northern Elephant Seal - Mirounga angustirostris
Photo by Howard Hall

The northern elephant seal is the largest seal in the world. The unique body structure of this mammal allows it to be an excellent open water swimmer and diver. Elephant seals can be identified by their large body size and the odd shaped nose (proboscis) found on the males. Elephant seals come to the shore at different times of the year to give birth, breed and to molt (shed their fur). These robust pinnipeds were once thought to be extinct, however, they did survive and the population is now growing!
