Giants of the Pacific Shores
The Northern Elephant Seal (Mirounga angustirostris) is one of the largest pinnipeds on Earth. Males can reach over 4,000 pounds and are famous for their trunk-like noses and deep, resonant calls across breeding beaches.
Once hunted nearly to extinction, they have rebounded in impressive numbers, forming large colonies along the Pacific coast.

Habitat
Elephant seals spend most of their lives at sea, coming ashore only to breed or molt. Large colonies form on sandy beaches, especially in California. Their range extends from Baja California to Alaska.
During breeding season, males defend harems and females give birth before returning to the ocean for foraging.
Behavior
Elephant seals are expert divers, plunging thousands of feet and holding their breath for up to two hours. Males compete aggressively during breeding season using loud bellows amplified by their trunk-like noses.
They are mostly solitary at sea but social on land. Despite their size, they are agile swimmers and key predators in the marine ecosystem.
