Elephant Seal

Scientific Name:
Mirounga angustirostris
Description

Large (males can grow to 4 m / 13 ft, weighing up to 2000 kg / 4,500 lbs) marine mammal with silvery brown coat, large eyes, and flippers. Males have a large, fleshy nose that resembles an elephant’s trunk, hence the name. Northern elephant seal population stretches from Baja California in Mexico to Alaska. We don't usually see elephant seals at Point Lobos, but one or two will occasionally visit for a short time before heading back out to sea where they spend the vast majority of their time. 

Behaviors

Hunts by diving for prey like fish, squid and eels, rarely spending more than four minutes on the ocean surface between dives. Returns to beaches to molt (shed upper skin and fur) every year.

Fun Facts

Although known for their fierce battles, male elephant seals more frequently use vocalizations to threaten or warn off competitors.

Habitat

Further Reading

The northern elephant seal (Mirounga angustirostris) is an occasional visitor to Point Lobos. The adult male, with its large elongated nose, is enormous at over 2 tons and up to 16 feet; females are significantly smaller. Like harbor seals, elephant seals lack ear flaps and move on land by flopping along on the belly. If you look closely at an elephant seal you notice black whiskers instead of the harbor seal’s white whiskers. Sand flipping is another clue. An elephant seal flips sand on itself to help regulate body temperature.

Elephant seals are characterized by extraordinary behavior. They spend 80% of their life at sea foraging, only coming ashore to molt (shed hair and skin) and to mate for adults, or to rest for subadults. While at sea they lead a solitary life and cover long distances in search of food. Elephant seals dive deep in search of food. They are the deepest diving pinniped known with an average dive to 1800 feet and a maximum recorded depth of over 5000 feet.

The occasional sightings at Point Lobos might include a recently weaned pup who hasn’t learned to successfully forage and is suffering from malnutrition. The Marine Mammal Center rescues them, nurses them back to health and then releases them to the ocean. Subadults might also haul out on our beaches to rest. Less frequently an adult male might visit Point Lobos. Older animals rarely appear at Point Lobos.

For almost guaranteed elephant seal viewing, drive a couple hours to one of the nearby mainland rookeries. Ano Nuevo State Park is about 2 hours north of Point Lobos. Piedras Blancas rookery, the largest rookery, is a little over 2 hours drive to the south on the Big Sur coastline near San Simeon. Elephant seals haul out to molt at different times based on age and gender, so you can always see some elephant seals at the rookeries. Visit one of the rookeries during the winter birthing and breeding season for an amazing nature experience. In the not too distant past, elephant seals were highly endangered. They now number approximately 85,000.
