Animal You | California Sea Lion | The California sea lion was described by René Primevère lesson, a French scientist, in 1828. It is grouped with the other sea lions and fur seals in Otariidae family. Lions, also known as sea lions differ with ear seals and proportionately larger front fins and pectoral muscles. With the sea lions and Galapagos sea lions disappeared Japan, owns the California sea lion Zalophus sex, derived from the Greek words za, the "intensive" and lophus, which means "peak this means is, the comb men distinguished above what the members genus . Traditional Galapagos sea lions and sea lions Japanese were classified as subspecies of California sea lions. Lines in Japan and California sea lions seem to have split off to 2.2 million years ago during the Pliocene. The California sea lions in the Galapagos sea lions in their sexual dimorphism differed more. The Steller Sea Lion is the nearest existing parent sea lion Zalophus is a sister taxon. California sea lions are sexually dimorphic differences in size, shape and color between the sexes. The face of the adult males can light brown in some areas. Although the species has a slender physique, adult men have strong neck, chest and shoulders. Adult males also have excellent rib them a "high forehead and thick bushy white hair. Too moons that are less developed by adult men in South America and the Steller sea lion have.
Otariid as the California sea lion resting on his front flippers to push themselves while swimming. This allows the animal turns and cultivate an attitude aerodynamics. When moving on land, sea lions can be converted before their hind flippers and crawl. Sea lions have color vision, even if it is limited to the blue-green region of the spectrum. Sea lions are sensitive hearing underwater, with a limit of detection of 0.4 to 32 kHz. Sea lions rely on their whiskers or vibrissae to touch and vibration detection of submarines. The beaches of California sea lions along the coast and on the islands of North America, Southeast Alaska Central Mexico. Mitochondrial DNA sequences in 2009, five different populations of California sea lions: the United States or with moderate Pacific, Baja California and the Western Pacific Tropical actions and south, center and north of the Gulf of California shares.
The stock of sea lions in the deep waters of the central bay is not analyzed. During the breeding season, sea lions gather on both sandy and rocky shores. In warm weather, they are near water. California sea lions can live in fresh water for a while, so near the Bonneville Dam on the Columbia River. In 2004, a sea lion was sitting on a healthy path in Merced County, California, about a hundred miles upstream from San Francisco Bay and a half miles from the San Joaquin River. California sea lions feed on a variety of seafood, mainly squid and fish, and occasionally clams. Commonly eaten fish and squid species are salmon, hake, Pacific whiting, anchovy, herring, redfish, sea lamprey, dogfish and squid market. California sea lions can eat alone or in small groups to large, depending on the amount of food available. Sometimes with other predators such as dolphins, porpoises and seabirds cooperation in hunting large schools of fish and sea lions sometimes follow dolphins use their hunting efforts.
Sea lions are prey of killer whales and large sharks. At Monterey Bay, California sea lions seem common food for fish-eating mammals transient orca pods. Sea lions can respond to the dorsal fin of a killer whale and remain vigilant, even when meeting with residents to eat peppers. Sea lions are common prey for white sharks. Shark attack by lions ambush while they sit on the surface. California sea lions breed herd from May to August, when they arrive at their breeding colonies. A male sea lions retains the general area for about 27 days. Women have more birth intervals, and so men are not born on their territory to the females Sea lions that area to make may not be trained to the sea or a nearby beach to collect. Begins prior to mating, women gather in "milling" groups of 2-20 persons. Women in these groups with each other and men assemble. The territorial and mating system of California sea lions as similar to a leak that women choose their partners, while you seem to be described as diverse. They prevent men who are too aggressive or energy. Male California sea lions have a breeding cycle of 12 months, consisting of a gestation period of nine months and three months of the actual implantation of the fertilized egg before birth in May or June shifted very long for this species is 21 days lions from California and more than 30 days sea lions in the Gulf of California.
Upon returning from a trip, call the women their young with separate calls involving the puppies from nature. The adult male California sea lions play no role in the upbringing of their children, but they take more interest in them than otariids adult males of other species, they are even seen swimming to help shield against small predators. California sea lions with a range of sounds to communicate. Territorial males are the strongest candidates and continuous and bark are produced constantly day and night - at the peak of the breeding season. Sea lions barking very quickly if it is enabled. Men can bark as threatening other males or courtshipMale lions are less vocal. The sound of a female lion like when calling his little called "pup-attraction call" as "strong" and "battle" section. Puppies also bleat or bark when reading or emergency. Californian sea lions can produce underwater sounds. Marine biologist Ronald J. Schusterman and his research associates have studied the lions cognitive skills. Sea lions have the ability simple syntax and commands as they learned sign language to understand artificial demonstrated. However, sea lions frequently used characters semantic or logical.
Because of their intelligence and ability to learn from California sea lions from circuses and marine parks mammals were used different tricks, such as throwing and catching. To balance ball trainer to throw a ball into a sea lion so it can accidentally balance or hold the ball on the nose, so. The California sea lions are used in military applications by the program of the U.S. Navy Marine Mammal, including the detection of mines and enemy divers.
