Their semi-annual sojourns to the shores of Point Reyes provide a unique opportunity to glimpse the lives and behaviors of these elusive ocean giants. Each year the northern elephant seal migrates farther than any other mammal in the world, traveling as many as 13,000 miles (about 21,000 km). This pattern, and the incredible amount of time spent below the surface, explains why so few of them have been seen in the open ocean despite their rapidly growing population. The second subpopulation, in the south Indian Ocean, consists of up to 200,000 individuals, three-quarters of which breed in the Kerguelen Islands and the rest in the Crozet Islands, Marion and Prince Edward Islands, and Heard Island. The first elephant seals on Año Nuevo Island were sighted in 1955, and the first pup was born there in 1961. Habitat: The elephant seal is almost entirely aquatic, coming ashore primarily to breed. The majority of primiparous females and a significant proportion of multiparous females mate at sea with roaming males away from harems. Today, there are approximately 160,000 northern elephant seals. On average female southern elephant seals weigh 400 to 900 kg (880 to 1,980 lb) and measure 2.6 to 3 m (8.5 to 9.8 ft) long, whereas bulls can range from 2,200 to 4,000 kg (4,900 to 8,800 lb) and grow to 4.2 to 5.8 m (14 to 19 ft) in length. They provide a range of services, from educational materials to studying the animals' needs. The elephant seal is the largest amphibious animal. Global efforts such as the Southern elephant seals as oceanographic samplers[38] and the Marine Mammals Exploring the Oceans Pole to Pole projects[39] have led to the collection of a large suite of long-term coupled behavioural-oceanographic data. Colonies once existed in Tasmania, Saint Helena, and the Juan Fernández Islands off the coast of Chile. Like all seals, elephant seals have hind limbs whose ends form the tail and tail fin. )[3]Macrorhinus elephantinus[4], The southern elephant seal (Mirounga leonina) is one of two species of elephant seals. In spring and summer seals also haul out at these areas for molting, as well as at some sites in Washington and British Columbia. Between 1988 and 1993, the population grew at a dramatic annual average rate of 32%. IMPORTANT NOTE: Due to the high volume of traffic out to the Lighthouse and Chimney Rock areas during the elephant seal pupping and mating season, the park will be operating a shuttle bus system from the Drakes Beach parking lot (usually from New Year's to Easter each year on weekends and holidays—weather permitting). As they dive, outside pressure compresses the air in their bodies. Before diving, elephant seals exhale; collapsing their lungs so there is little air to be compressed. Imagine being able to live in such extremes! The majority of these rookeries are in California and northern Baja California, ranging from Point Reyes National Seashore, California to Isla Natividad, Mexico. [45] The world population was estimated at 650,000 animals in the mid-1990s, and was estimated in 2005 at between 664,000 and 740,000 animals. Each of the "feet" can deploy five long, webbed fingers. Female philopatry and male dispersal are thought to be typical of mammalian species, although detecting genetic dispersal events remains difficult. A southern elephant seal's eyes are large, round, and black. Elephants are grayish to brown in color, and their body hair is sparse and coarse. Adult males use their large, inflatable noses during the winter breeding season to resonate sound when vocally threatening each other. These activities occur at rookeries that are located on offshore islands or remote mainland beaches. Males commonly vocalize with a coughing roar that serves in both individual recognition and size assessment. Male elephant seals reach 16 feet in length and weigh up to 4,000 pounds. Northern Elephant Seal Range Species Fact: Adult males use their large, inflatable noses during the winter breeding season to resonate sound when vocally threatening each other. The first moulting accompanies weaning. Sensitive resources such as birds and plants are also affected by elephant seals. They lack external ear flaps and move on land by flopping on their bellies. The western snowy plover, a Federally threatened species under the Endangered Species Act, breeds on few California beaches. [25] After being born, a newborn will bark or yap and its mother will respond with a high-pitched moan. The least successful males have no harems, but they may try to copulate with a harem male's females when the male is not looking. (Sexual dimorphism is the difference between males and females).

The southern elephant seal (Mirounga leonina) is one of the two species of elephant seals. In this paper we discuss a further expansion of the pupping range of the northern elephant seal to Shell … Weaned pups and juveniles may fall prey to orcas. This number will initially be answered by an automated attendant, from which one can opt to access a name directory, listen to recorded information about the park (i.e., directions to the park; visitor center hours of operation; weather forecast; fire danger information; shuttle bus system status; wildlife updates; ranger-led programs; seasonal events; etc. While hunting in the dark depths, elephant seals seem to locate their prey, at least in part, using vision; the bioluminescence of some prey animals can facilitate their capture.
