The California sea lion (Zalophus californianus) is a coastal eared seal native to western North America. It is one of six species of sea lions. Its natural habitat ranges from southeast Alaska to central Mexico, including the Gulf of California. California sea lions are sexually dimorphic; males are larger than females, and have a thicker neck, and a protruding sagittal crest. They mainly haul-out on sandy or rocky beaches, but they also frequent manmade environments such as marinas and wharves. California sea lions feed on a number of species of fish and squid, and are preyed on by orcas and great white sharks.
Description
California sea lions are large animals, with an average length of 2.5–2.7 m (8.2–8.9 ft) long and weigh up to 523 kg (1,153 lb), while females are typically around 2.1 m (6.9 ft) and weigh up to 100 kg (220 lb). Females and juveniles have a tawny brown pelage, although they may be temporarily light gray or silver after molting. The pelage of adult males can be anywhere from light brown to black, but is typically dark brown. The face of adult males may also be light tan in some areas. Pups have a black or dark brown pelage at birth.
Distribution and habitat
California sea lions are found along the coasts of western North America, from southeast Alaska to central Mexico, including the Gulf of California. They are most common in the waters off California, Oregon, and Washington. California sea lions are found in a variety of habitats, including rocky beaches, sandy beaches, and kelp forests. They are also found in manmade environments, such as marinas and wharves.
Diet
California sea lions are carnivores and their diet consists mainly of fish and squid. They will also eat other marine animals, such as sea otters, seals, and seabirds. California sea lions are opportunistic feeders and will eat whatever is available.
Behavior
California sea lions are social animals and live in groups called herds. Herds can range in size from a few individuals to a few hundred. California sea lions are active during the day and night, but are most active during the day. They are excellent swimmers and can travel long distances in water.
Reproduction
California sea lions are polygynous, meaning that males mate with multiple females. The breeding season is in the spring and summer. Females give birth to 1-2 pups after a gestation period of 11 months. The pups are born with their eyes open and are able to swim within a few hours of birth. Pups are nursed by their mothers for about 6 months.
Threats and conservation
California sea lions are not currently considered to be endangered, but they are threatened by a number of factors, including habitat loss, pollution, and hunting. In some areas, California sea lions are also a nuisance to humans, as they can damage property and livestock.
Conservation efforts are underway to protect California sea lions. These efforts include creating protected areas, reducing pollution, and educating people about the importance of sea lions. With continued conservation efforts, California sea lions can be protected from extinction.
