Northern Elephant Seal

Mirounga angustirostris

Also known as Northern Sea Elephant

Northern elephant seals spend up to ten months a year deep in the Pacific Ocean, diving thousands of feet down to hunt fish and squid before returning to coastal beaches to breed and molt. Massive bulls command harems on sandy shores with resonant, rhythmic roars amplified by their inflatable proboscis. Having recovered from near extinction in the late nineteenth century, their breeding colonies now thrive along the western coast of North America.

Why interaction risk is high
Massive size and aggression during breeding make them hazardous; maintain a distance of at least 100 feet.
Why it is dangerous
Massive weight and intense territorial aggression during breeding can cause severe crushing injuries or deep puncture wounds.
How to recognize a risky encounter
Look for gigantic, greyish-brown bodies and males featuring a large, overhanging inflatable proboscis.
What to do
Never walk between a seal and the ocean, and always view rookeries from designated boardwalks or overlooks.
What to notice
Large colonies assemble on sandy beaches along California and Baja California primarily from December through April.
Support conservation
Keep noise levels low, stay on established paths, and avoid any movement that causes a herd to panic into the surf.
Responsible observation
  • Keep Distance: Maintain at least 100 feet (30 meters) of space from resting or breeding animals.
  • Watch for Signals: Back away immediately if a seal raises its head, vocalizes, or moves toward you.
  • Leash Dogs: Keep pets far away to prevent severe injuries to pets or stress to seals.
