Sea lions

family Otariidea, Sea lions use sexual reproduction meaning they require a mate to produce offspring. There are 6 living sea lion species in the world. The Japanese Sea Lion, Zalophus japonicas, became extinct within the 1970’s. The Steller sea lion has the largest sea lion population and lives in the Northern Pacific. The California sea lion is the best known and seen in zoos and the circus. An average weight of a sea lion is 400 pounds and having a length of 6 feet long. Sea lions have a variety of

Zealand sea lion (formerly known as the Hooker’s sea lion) is the most threatened sea lion species in the world. A Scope Bycatch is a significant issue affecting marine mammals in New Zealand. This paper will focus on the effect that squid trawling has on the declining population of the New Zealand sea lion. This paper will address whether current mechanisms that seek to protect the New Zealand sea lion are robust and will recommend options for reform. B Background Historically, New Zealand sea lions

Seals and sea lions are not the same Even though both sea animals are professional in the water they have a lot of differences. Like sea lions have external ear flaps and seals have a small holes for ears. Sea lions have a flexible pelvic girdle that enables them to move more easily on the land. To more more easily they rotate their hind flipper underneath their bodies to walk other animals. They use their front flippers to propel forward in the water. Sea lions also sleep with all of their flippers

Seven species of sea lions exist in the world. They are categorized into a group of animals that are known as pinnipeds. The modern Sea Lions body was built for marine life (life in water). They have torpedo shaped torsos that are smooth with short and thick hair, for easy land and water gliding. Their torsos are pale in colour and the rest of their body is a dark grey or dark brown, depending on the seas lion species. Their flippers are very strong and powerful, there are 2 flippers at the front

The California Sea Lion is an amazing animal but because of overfishing their population is starting to decline. This is an endangered animal. The California sea lion is a sleek creature that is faster than any other sea lion or seal. Sea Lions are called lions because they “roar” like a lion to communicate. Groups of sea lions are called colonies or rookeries. The California Sea lions scientific name is Zalophus californianus. It lives in western North America,Canada, and the gulf of Mexico. Its

Research Report Many people don’t notice that sea lions are starting to die out. But why? Why are sea lions starting to die out? Two reasons, poison in algae and the ocean not providing enough food for sea lions. One reason why sea lions are dying is because of poison in algae. The poison causing the sea lions to die is called domoic acid. Domoic acid is produced by algae called Pseudo Nitzschia and forms when the Pseudo Nietzsche bloom. When the sea lions eat the algae, the domoic acid kills their

Breeding and foraging behavioural adaptations of the Australian Sea Lion (Neophoca cinerea) Introduction The Australian sea lion, Neophoca cinerea of family Otariidae is the sole extant species of its genus and the only endemic pinniped found in Australian waters, ranging from coastal Western Australia to Southern Australia (Kirkwood & Goldsworthy 2013; Lowther et al. 2012). Unique in its non-annual, temporally asynchronous breeding cycle across adjacent colonies, prolonged breeding and lactation

Sea lions are extremely social animals, more so than just about any on earth. Sea lions often live in in very large colonies that can have up to a thousand of members. The males are much larger and dominate when it comes to social structure of Sea Lions. The sea lions build a bond based on the fact that they have young to care for or that they are pregnant. California sea lions are extremely gregarious and form large aggregations when on land. Individuals lie close to each other, or even on top of

Californian Sea Lions have roamed the docks of San Francisco, California for over 25 years now. Though the Sea Lions have only been here for a short period of time, the sleek mammal has become a welcoming member of the pier harbors, playing a significant role in attracting tourists from around the globe. Shortly after the Loma Prieta earthquake that hit San Francisco in 1989, Sea Lions began hauling out on Pier 39’s K-Dock; and by January of 1890, the K-Dock was flooded by the marine animals. Since

Sea Lion Pups Deliver More Bad News on Warming Oceans Baby sea lions are washing up on to beaches in California in unprecedented numbers—stranded, starving, and sick—leaving wildlife rescuers overwhelmed. Although small numbers of unfortunate pups have always suffered this fate, the last 3 years have stood out with numbers that are “particularly high; and it looks as though … 2015 will be the highest ever recorded,” according to Dr. Andrew Trites, director of the Marine Mammal Research Unit at the
