About Elephant Seals
Seals on the sand
The northern elephant seal is the second largest seal in the world, after the southern elephant seal. Much more agile in their ocean environment, an elephant seal moves on land with considerable effort, by using its front flippers and belly. Adult males are 14 to 16 feet (4 to 5 m) in length and 4,000 to 5,000 pounds (1,400 to 2,300 kg) in weight. The females are much smaller at about 9 to 12 feet (2.5 to 4 m) in length and weigh 900 to 1,800 pounds (400 to 800 kg). Pups are 3 to 4 feet (1 m) long at birth and weigh about 70 pounds (32 kg).

Month by Month at the rookery
The number of seals at the rookery peaks three times during the year: in late January when most births have occurred, around the first of May at the peak of the juvenile/adult female molt, and in late October during the fall or juvenile haul-out. The annual cycle begins in November with the arrival of mature males at the end of the month.
Why Elephant Seals Are Awesome
- Elephant seals take their name from the large proboscis of the adult male (bull), which resembles an elephant’s trunk.
- Male elephant seals weigh as much as a small truck or cargo van.
- Elephant seals are shielded from extreme cold more by their blubber than by fur.

Where is the Elephant Seal Viewing Area?
Why did they start coming here?
As the elephant seals rebounded from near-extinction, they first re-established colonies on the islands off the shore of Baja California and California. When these rookeries became too crowded, they began colonizing mainland beaches.
They began coming here in 1990. The Piedras Blancas Rookery was populated from San Miguel Island, San Nicolas Island, and Ano Nuevo. Elephant seals like large sandy beaches that do not have a significant human presence. The rocky areas in the shallow waters provide the weaned pups some protection from breakers while they are learning to swim. The kelp forests, which are not far off shore, and the shallowness of the sea bed could help the seals avoid predation since shark attacks are more common in deeper water.
Do they go out to eat at night?
The elephant seals do not eat while they are at the rookery. They live off their blubber, relying on it to provide water and energy. While they are ashore for birthing and breeding, the females will lose 30 to 40 percent of their body mass. Large males, who fast for 3 months during the breeding season, will also lose about a third of their body weight.
Weaners practice at night to learn to swim and dive in preparation for the dark of the ocean depths in which they will feed.
