Elephant Seal Homecoming Days

In January 2008, a couple of thousand female elephant seals began returning from the far reaches of the North Pacific Ocean to give birth to their pups on the beaches of Año Nuevo State Reserve in Northern California.
To celebrate this amazing migration, we invited the TOPP community to witness and learn about the seals’ 21,000-mile annual journeys during Elephant Seal Homecoming Days, sponsored by TOPP, California State Parks, and California State Parks Foundation.
The tracking of these seals began when researchers from Dan Costa’s lab at the UC Santa Cruz Long Marine Lab attached satellite tags to several female elephant seals during the summer of 2007. For nine months, the seals lived and foraged along the rich edges of the massive eddies that swirl across the North Pacific.

We followed ten named elephant seals back to shore as researchers posted blogs about their arrival, their pup's birth, and tag removal.
When TOPP.org debuted in July 2007, we chose one seal to represent her species and named her Penelope. The other nine seals were given names from their history, or the history of their surroundings. Their names are Myoceen, Mukurma, Isabel, Clara, Cheddar, Coya, Annie, Guadalupe, and Flora. The details of their history were put on their trading cards.
When we tagged 22 new seals in March 2008, Karen Maor's fourth-grade science students at Hillbrook School in Los Gatos, CA named 10 new seals: Tidepool, Steele, Lulu, Isla, Baja, Calie, Nuevo, Pinni, Mirounga and Diel.
Elephant Seals Homecoming Days was made possible by a grant from the California State Parks Foundation.

FUN FACT: Northern elephant seals were hunted nearly to extinction in the 1880s. They are protected by Mexican and American laws, and have made an amazing comeback, from 100 that survived at Guadalupe Island off Mexico, to more than 160,000 today.- www.whaletimes.org
FUN FACT: Northern elephant seals eat squid, octopus, fish and sometimes even small sharks. Southern elephant seals have a similar diet. - www.whaletimes.org
National Park Service: Discovering Northern Elephant Seals FUN FACT: Northern elephant seals migrate farther than any other mammal on earth, and are the only mammals known to make two migrations each year. After the breeding season, they migrate to feeding grounds in the northern Pacific Ocean. In the summer, they return to the beaches to molt, then migrate back to feeding areas until the next breeding season. Every year, they travel about 21,000 miles (33,800 km). - Monterey Bay Aquarium
FUN FACT: The male’s large nose is a secondary sexual characteristic. Large body size, large nose, and a deep booming voice sometimes serve to intimidate challengers, so that energy-depleting fights can be avoided.- Friends of the Elephant Seal
FUN FACT: Males can live 14 years; females, 20. But only a few live that long. Only one in seven pups lives to 4 years old. - Friends of the Elephant Seal
University Research Support for High School Science Teachers FUN FACT: Male elephant seals compete for females during breeding season, from December through March. The strongest, most aggressive male generally has access to more females. They compete for the females through visual and vocal threats, and occasionally physical battles. - www.whaletimes.org
Elephant Seal Tagging: Yesterday and Today. While tagging in Año Nuevo in 2006, TOPP researcher Dan Costa recalls his early days of studying elephant seals.FUN FACT: Once each year, in the summer, elephant seals come ashore and shed the first layer of skin and their fur. The skin and fur come off in sheets as new skin and fur replace the old. - Monterey Bay Aquarium

Año Nuevo State Reserve: FUN FACT: Northern elephant seals can stay underwater for 40 minutes, sometimes longer. They normally dive 1,000 to 2,000 feet, but can go as deep as 5,000 feet. When they dive, they swim only for the first one hundred feet, coast for the remainder and sometimes nap on the way down. - http://www.whaletimes.org/whaelsl.htm

FUN FACT: With all that blubber, elephant seal bodies are designed to keep warm in cold water. On land, sand flipping helps them keep cool; they also flip sand when they’re under stress.- Friends of the Elephant Seal
