December 15th, 2015
Just 35 minutes north of Cayucos on Highway 1, exactly 26.6 miles is where you can find the Piedras Blancas Elephant Seal Rookery.
The large bulls are just starting to arrive and are fighting to claim their dominance. A calloused shield and a thick layer of blubber protect the neck and chest area of a large bull. Fights can last from just a few minutes to half an hour, depending on how evenly matched the bulls are. It is quite a sight to see such large mammals grunting and proclaiming their territory against each other. The males can weigh up to 3,000 to 5,00 pounds and grow up to 14-16 feet in length. Adult Females are 9 to 12 feet in length and weigh between 900 and 1,800 pounds.
Pregnant females give birth to pups weighing 60-80lbs, Seagulls do their part and clean up the afterbirth. The peak of birthing season is January. Females are technically pregnant 11months and have a 7-month gestation. The reason for the difference in gestation to birth is that the fertilized egg does not implant in the wall of her uterus for about four months a rare phenomenon called "delayed implantation". The first pup of the season was born just a few weeks ago.
