About California Sea Lions
California sea lions are known to be intelligent, playful and a common sight in Monterey Bay. Easily identified by their brown coat, small ears, broad flippers and loud bark. Sea lions often haul themselves out of the water on sandy beaches, rocky shores, jetties, piers or docks.
California sea lions are extremely social and often gather together in large groups. They are fast, agile swimmers and are often seen playing, splashing and porpoising. Sea lions main predators are killer whales and sharks.
In spring California sea lions gather at the breeding areas called “rookeries”. Male sea lions (bulls) defend their beach territories while females arrive and shortly thereafter give birth to a single pup. Within two to three weeks after giving birth, females mate with area bulls to ensure next year’s pup. At birth pups are about two and a half feet long, weigh about 13 pounds and are able to crawl around within 30 minutes of being born. Females will leave their young pup to search for food and are able to find the pup on a beach full of hundreds of pups through vocalizations and smell. During mom’s absence, pups gather in groups called “pup-pods” and spend time sleeping, playing, exploring and swimming in the tide pools.
