Australian Sea Lion

Mia Orlich

The Australian sea lion, or as it's known scientifically as Neophoca Cinerea, is an endangered species



Australian sea lions are known to live on sandy beaches close to the ocean, they are usually found on the coast lines and islands of southern and western Australia.

Community Interactions

Since Australian sea lions are a predator they rely on fish as their food source. They are know to eat a variety of smaller fish such as the whiting, rays, small sharks, squid, cuttlefish, fairy penguins, blue-throated wrasse and octopus.

Feeding Relationships

Australian sea lions are carnivores, Eating smaller fish and some birds.


The Australian sea lion eats fish. They live on beaches and islands near the ocean and spend a lot of their time in the water, but unlike most other pinnipeds they are very capable out of the water.

Population Dynamics

The depletion of the Australian Sea Lion is density independent because the harm done to the species is all human related and does not affect the carrying capacity of its habitat.

Human Impact

The decrease in the Australian sea lions all ties back to humans, Many Australian sea lions are killed by poachers who take their skin to sell, another factor is fish nets, the sea lions see the fish in the fish nets and try to eat them and end up getting stuck in the nets, Lastly many fisherman kill the sea lions because they try to get into their traps and take their fish.

Cells/Cell Respiration

The Australian sea lions use cellular respiration. Since the Australian ea Lion is not a producer it cannot and does not have the need to produce its own food which is why it is incapable of using photosynthesis.

DNA/Cell Reproduction

Australian sea lions reproduce using sexual reproduction. They typically have one pup and they usually have multiple mates throughout their lives. The pups usually stay with their mother for about 15-18 months. The Australian Sea Lion uses both meiosis and mitosis, meiosis strictly makes sex cells while mitosis makes the rest.


The Australian sea lions kingdom is animalia. Its phylum is chordata. It is part of the mammalia class and its order is carnivora. The Australian sea lions family is the otariidae. Its genus level is neophoca while it is the only animal in that genus level it is related to all eared seals that are on lower classifications like the Steller sea lion, South American sea lion, New Zealand sea lion, California sea lion and other eared seals. Scientific research has some idea of how sea lions came to be but they do not have the whole story, many researchers believe that the sea lion was first a land animal but developed webbed feet and flippers to survive in the water due to a lack of food on land.
