Northern Elephant Seal

CAN BE FOUND IN:

Northern Elephant Seal

Mirounga angustirostris

Appearance

The northern elephant seal is the largest seal species in the northern hemisphere. Adult males can weigh up to 2,300 kilograms and are known for their large, inflatable noses that resemble an elephant’s trunk. Females are much smaller, usually weighing up to 600 kilograms. Both have large, round eyes and sleek brownish-grey fur that darkens when wet. 

range & habitat

Northern elephant seals are found along the Pacific coast of North America, from Alaska to Baja California. They spend most of their lives in the open ocean, diving to great depths to hunt squid and fish. They come ashore twice a year, once to breed and once to molt. In British Columbia, elephant seals are most often seen resting on remote beaches or rocky islands along the outer coast. 

reciprocal relationships

Elephant seals are known for their extreme nature compared to other seals. They are extreme divers and extreme navigators. They can dive to depths of 1,500 metres and hold their breath for over an hour. This skill allows them to hunt for fish that live in deeper waters. As they dive deep and come up for air, elephant seals help transfer nutrients between the different ocean zones. This helps improve marine productivity and helps many species thrive.  

They also traverse far distances in the ocean, known for being away from shore for months on end. When they return to shore, it is often for molting or pupping seasons. Keeping a respectful distance from these sites keeps these incredible animals safe from disturbance.  

These seals are at risk of oil-spills, improper use of fishing equipment, and environmental contaminants. As a result, we have observed a decline in seal populations over the years. If you witness any incidents involving marine mammals, please call the marine mammal hotline.
