Pinnipedia California Sea Lion CALIFORNIA SEA LION Zalophus californianus meaning of Latin name: with crest and of California DESCRIPTION: California sea lions are known for their intelligence, playfulness, and noisy barking. Their color ranges from chocolate brown in males to a lighter, golden brown in females. Males may reach 1,000 lbs. (more often 850 lbs., or 390 kg) and seven feet (2.1 m) in length. Females grow to 220 lbs. (110 kg) and up to six feet (1.8 m) in length. They have a "dog-like" face, and at around five years of age, males develop a bony bump on top of their skull called a sagittal crest. The top of a male's head often gets lighter with age. These members of the otariid or walking seal family have external ear flaps and large flippers that they use to "walk" on land. The trained "seals" in zoos and aquariums are usually California sea lions. RANGE/HABITAT: BEHAVIOR: California sea lions are very social animals, and groups often rest closely packed together at favored haul-out sites on land, or float together on the ocean's surface in "rafts." They are sometimes seen porpoising, or jumping out of the water, presumably to speed up their swimming. Sea lions have also been seen "surfing" breaking waves. California sea lions are opportunistic eaters, feeding on squid, octopus, herring, rockfish, mackerel, and small sharks. In turn, sea lions are preyed upon by Orcas (killer whales) and great white sharks.

General Information The sea lion lives off the west coast of North America. It is a vertebrate which means it has a backbone. The sea lion lives in warm climates and migrates south to warmer climates when the temperature cools down. It is a mammal which means it has mammary glands that produce milk for its young. The physical features are growth of 5-11 feet in length and weight from 77-2400 lbs. Usually, the male is bigger than the female. The body of the sea lion is shaped like a torpedo so it can swim faster and easier. The sea lion has whiskers, a little fur, blubber, and fins. Zoo Observations The sea lion was not at the zoo. The pool was being cleaned. Niche/Habitat The sea lion's habitat is mostly water. It also can live on land for a long period of time. On land it must be on a shoreline where it is rocky. The climate must be warm. These animals do not have to migrate so far south because they are in California. They migrate south to the tip of South America where it is warmer when the temperature cools down.

References Physical Appearance The pictures seen here are Stellar sea lion pups, but when they reach their adult size these animal are the largest of all the eared seals. The average length of an adult male is 300 cm, whereas a female is 250 cm. The big difference between males and females are their weights. A full grown male can weigh up to 1000 kg and a female is only 270 kg! Adult fur is light to reddish brown in colour and adult males develop thick neck muscles that are covered by long coarse hair, that looks like a mane, hence the name "sea lion". Distribution Stellar sea lions live in the Pacific northwest and can be found from San Miguel Island in southern California, to Alaska, to the Sea of Okhotsk, near Japan. Along the California coast north to Vancouver Island, British Columbia, there lives a another species of sea lion, the California sea lion ( Zalophus californianus ). The California sea lion is often mistaken by an untrained eye for the Stellar sea lion.

A: There are so many different seal species in the world that its difficult to say what they can eat in a day. The harbour seals at the Vancouver aquarium eat an average of 8.1 percent of their body weight each day. That's a lot of food! If a 100 pound human had to eat eight percent of his weight each day it would mean consuming about eight pounds of food. The average lifespan of all pinnipeds (seals, sea lions and walruses) is about 15-25 years. Seals (received November 12 from ? on Vancouver Island)

Contacts Licenses/Permits Regulations News ... www.adfg.state.ak.us Steller's Sea Lion The Steller's (or northern) sea lion Eumetopias jubatus ) inhabits the north Pacific Ocean and is the largest member of the family of Otariidae, or "eared seals." Sea lions differ from hair seals (harbor seals, ringed seals, ribbon seals, bearded seals, and spotted seals) in that sea lions have external ears and rear flippers which turn forward allowing them to "walk" with a gait similar to land mammals. They are called sea lions because they resemble the terrestrial lion of Africa and Asia. Large adult male Steller's sea lions have disproportionately large necks and shoulders. This, coupled with longer, coarser hair on the neck and shoulders, gives them the appearance of having manes, as do lions. General description: At birth, the sea lion pup's coat is chocolate brown with a frosty appearance because the tips of the hair are colorless. Color gradually lightens as the animal ages and periodically molts. Most adult females are a yellowish, cream color on the back, although some remain darker. Nearly all males stay darker on the front of the neck and chest; some are even a reddish color. Males and females have a marked size difference. Weight at birth is 51 pounds (23 kg), and body length is 45 inches (112 cm). Females grow rapidly during the first four years but slow by the fifth year, with little growth after age 6. Males continue to grow until the eleventh year. Although there are variations, most females reach maximum size by the seventh year, and males reach adult size by the twelfth year. The average weight of an adult male is 1,245 pounds (566 kg), and the body length averages 10 2/3 feet (282 cm). Adult females average 579 pounds (263 kg) in weight and 8 2/3 feet (228 cm) in length. Although only 20 percent longer, the average adult male weighs over twice as much as the average adult female.

Home TV Radio Talk ... Programmes Last Updated: Friday, 13 February, 2004, 02:20 GMT E-mail this to a friend Printable version Pacific sea lion collapse probed By Jonathan Amos BBC News Online science staff The sea lions used to number hundreds of thousands Scientists believe they are closer to understanding why the populations of Steller sea lions and other mammals have collapsed in the north Pacific. The sea lions have seen their numbers fall by more than 80% since the 1970s. The North Pacific Universities Marine Mammal Consortium says the animals appear to have switched to eating fish with a very much lower fat content. This means the sea lions cannot build up sufficient blubber to survive and breed in their cold environment. "In 1977, there was knife-edge change - it cut right through the ecosystem," the consortium's director Dr Andrew Trites told the BBC. "It not only affected the seals and sea lions, it also affected the shrimps, the crabs, the salmon - a whole suite of species flipped overnight in their abundances." Steller sea lions are found from Japan through Russia, Alaska, British Columbia and down to California.

The sea lions can carry out repeated dives to great depths without tiring The specially trained mammals have been deployed to the region to protect US and British warships against attacks from underwater saboteurs and mines. These whiskered warriors are even capable of clamping a floating marker to the legs of an intruder, alerting troops to his position, who can then move in and haul the attacker out of the water. The British naval commander in the Gulf, Rear Admiral David Snelson, warned on Monday that possible al-Qaeda attacks on warships in the region was the biggest security threat facing his forces as they prepare for a possible war with Iraq. Three years ago 17 US servicemen were killed when the USS Cole was attacked in the Yemeni port of Aden by al-Qaeda operatives using an inflatable boat packed with explosives.

Sea Lions Best of San Francisco's Fisherman's Wharf Our favorite thing about our least favorite place, Fisherman's Wharf, are the sea lions that own Pier 39. Hidden on the left side of Pier 39 (enourmous shopping mall) are hundreds of sea lions basking in the sun. They have taken over a marina that held boats and are an incredible natural attraction. Just walk to the end of Pier 39 on the left side along the backs of the stores and behold the sea lions. They lie there, in the sun and bark- arf arf! Many people crowd around to see the sea lions, but many others never even realize they are there. If you visit the wharf, don't miss the sea lions! Tacky and over-priced, but clever we noticed this mini bungee jumping for kids on our last hideous visit to Fisherman's Wharf. For $6, your child can be suspended from elastic cords and jump on a trampoline. Stupid as this sounds, it is a pretty cool thing also just to the left of Pier 39 in the courtyard area. The ride is called "Fearless Flyer" and it was very fun for kids as shown above. Want a great hotel and a reasonable price? Check out our readers'

South American Sea Lion (Otaria flavescens) Distribution and Numbers Also known as the Southern sea lion, and referred to by some scientists as Otaria byronia , the South American sea lion is found along the coasts and off-shore islands of South America. The limits of its range are Zorritos in northern Peru and Ilha dos Lobos in southern Brazil, although wandering individuals have been found as far north as Ecuador and the Galápagos Islands. Population figures for the species are incomplete. However the overall population is estimated to be about 265,000, consisting of roughly 30,000 in Peru, 128,500 in Chile, 90,000 in Argentina, 12,000 - 15,000 in Uruguay, 3,000 in the Falkland Islands, and a few hundred in Brazil. The populations in Uruguay and the Falkland Islands are decreasing rapidly while in most of Argentina and Chile they are increasing at an annual rate of around 3%. The species has no breeding colonies in Brazil, the small number of individuals found there having originated from the Uruguayan and Argentinean colonies to the south. Photo: Miguel Iñíguez

New Zealand Sea Lion (Phocarctos hookeri) Distribution and Numbers One of the rarest and most endangered sea lions, the New Zealand sea lion (also known as the Hooker's sea lion) is found only in New Zealand and breeds almost exclusively on New Zealand's subantarctic islands, the main breeding colony being located on Dundas Island in the Auckland Islands. Over 95% of the total pup production for the species occurs in three colonies in the Auckland Islands, within a very localised area (less than 7km apart). New Zealand sea lions haul out in an area ranging from the Australian subantarctic Macquarie Island to the southeast coast of South Island, New Zealand. Individuals are also occasionally seen on New Zealand's North Island. The total population was estimated at 12,000 - 14,000 before a mass mortality event of unknown cause resulted in the deaths of a large number of the species in January 1998. Photo: Nathan McNally, University of Otago Status Although the New Zealand sea lion was extensively killed for its hide and oil in the 19th century and, to a much lesser extent, the early 20th century, commercial killing of the species has been illegal in New Zealand since 1893.

The differences between seals and sea lions Here's how you can tell the difference between seals and sea lions, even though the differences are pretty small. They may look very much alike, but are seals and sea lions related? What are the differences? Seals and sea lions both belong to the scientific order Pinnipedia. The name literally means fin-footed. There are 33 living species of pinnipeds. They are all warm-blooded mammals that have a streamlined torpedo body, enabling them to swim and dive gracefully. Both seals and sea lions have flippers that act as rudders, helping them to steer in the water. However, although they are very suited to the marine environment, pinnipeds spend part of their life in the water and part on land, which sets them apart from the other marine mammals (whales). They live a nomadic lifestyle, spending months out at sea and then returning to land to rest. Scientists have divided the pinnipeds into three families: earless seals (Phocidae), eared seals (Otariidae), and walruses (Odobenidae). bodyOffer(31884) The earless seals are the phocids. They are what you would think of as a seal. They are called earless because they lack ear flaps. However, this does not mean they are deaf. Seals have tiny openings, which are called pinnae, that serve as ears. There are eighteen species of seals.
