Promoting stewardship and understanding of the rich marine life and unique marine environment of the Central Coast

The Northern Elephant Seal, Mirounga angustirostris , is an extraordinary marine mammal. It spends eight to ten months a year in the open ocean, diving 1000 to 5000 feet deep for periods of fifteen minutes to two hours, and migrating thousands of miles, twice a year, to its land based rookery for birthing, breeding, molting and rest. The Piedras Blancas rookery, on Highway 1 seven miles north of San Simeon on the California Central Coast, is home to about 15,000 animals. The area is open for viewing every day of the year and there is no admission fee or reservation required.

If there is something you want to know about elephant seals, or about other marine mammals that inhabit this area of the California coast, please ASK US.

December through March

Birthing, Battles, Breeding and the Start of a New Adventure

In December the older males, sub-adult and adult, arrive. They challenge each other for dominance over a section of the beach through a combination of fighting and, more often, intimidation. Beginning in mid-month the pregnant females arrive and the first birth occurs not long before Christmas, the rate of births peaking in mid-January with approximately two births per hour on the beaches adjacent to the parking lot.

With the births come the gulls eager for the after birth. The pups are black, noisy and active with a strong interest in the milk from their mother that will take them from approximately 70 pounds at birth to over 300 pounds in four weeks. The males continue to battle because with dominance comes breeding rights to the females in the dominated area. Breeding takes place near the end of the nursing period and then the mother.

The mothers, newly pregnant, leave for the open ocean and the weaned pups are on their own. By early March they own the beach with a occasional exhausted and slender adult male resting up before his trip to the Aleutians. The "weaners" are attractive and curious and, no longer hassled by the protective mothers, go out into the shallow protected waters among the rocks off shore and build their swimming skills and muscles before they too start their marine life.
