California Sea Lion Research Paper

Lionfish are native to the Indo-Pacific waters and the Red Sea. However, recently they have been invading the Atlantic Ocean. This has been affecting the reef systems in this area. Since they are not native to this part of the world, they have begun to affect the ecosystems. They have also had an effect on commercial fishing. However this is mostly on local fishing.

California Sea Lions are found off the west coast primarily in the Channel Islands off the California coast. Males can reach up to 850 pounds,

Southern sea otter lives in kelp forests (a type of seaweed) along the Pacific coast, mainly off the coast of California. The marine mammals consume on average one-fourth of its weight daily including sea urchins, which are vital to support the kelp forests. By the result of sea otters preying on sea urchins, the consumption of kelp by sea urchins are kept at a constant rate allowing the forest to grow and thrive. This is highly important for biodiversity in the sea that is provided by the kelp forest, which is a key component of the three principles of sustainability. There are three ways that human can do to help prevent the premature extinction of southern sea otters. First, ethical issue that consists of the species being seen as vital

supplies. This included salmon, whale, sea otter, sea lion, porpoise, and seal. The abundance of

Steller sea lion pups possess thick rough coats with a mostly dark appearance. After the first molt, their color lightens. The complexion of female and male Steller sea lions is a golden-brown to a reddish brown. They have a somewhat darker shade in their chest and abdomen. Steller sea lions also display sexual dimorphism which means that the males are remarkably larger than females. Similar to all pinnipeds, the Steller sea lions have whiskers to sense prey. They also molt every year which parallels to other pinnipeds, and they are mainly insulated by blubber. In addition, they have flippers that are used for locomotion. Their sensory organs are accommodated to operate both underwater and in the air, but because they are mammals they have to come up to the surface in order to breathe.

Hypothesis: The highways which cut through the great forest and mountain ranges of California are a large contributor to the population of California's Mountain Lions due to the division of natural environmental habitats. Human communities also play a role in Mountain Lion population stunts because human neighborhoods are ever expanding.

The seal lion population has decreased by eighty-percent. The weird thing is that there is no bodies to prove that the seal lions are gone. Some of the causes of the decrease could be fisherman, pollution, and killer whales. The sea lions could also be starving to death. The fisherman are taking all of their sources of food. But, in Alaska the sea lions are thriving and the whales are not. Thirty years ago ninety percent of the whale population was gone in Alaska. This resulted in an abundance of more krill and plankton, which lead to more pollock and herring. The sea lions ate the herring the most as it was healthier and kept them full. But, when the herring population decreased the sea lions had to eat pollock. Pollock is the “junk food

The reading and the lecture give information to explain the reasons that lead to rapid decrease in the sea otter number. While the reading looks at the topic ffrom one perspective the reading challenged the idea illustrated in the reading passage.

Lionfish have a wide spread diet, meaning that they consume several different species. In fact, they have even threatened species that scientists and marine biologists have yet to discover. If that was not already a gigantic problem, they also digest several other fish only found in certain parts of the ocean. This means that without much effort, various specimens of fish will go extinct. This will ultimately end with empty coral reefs and void like oceans, devoid of life as a total. An article titled 'Twilight Zone' Horror Story: Lionfish prey on Unknown Fish Species, clearly states

Females are tan and males are chocolate brown. Male sea lions can reach uq to 6-8 feet and weigh 440-880 pounds. Females are 5-6 feet and can weigh 110-240 pounds. Their eyes are very large. They have 40-60 whiskers and 34-38 teeth. Their hind limbs have 5 digits. On three of those there are nails. When swimming their hind limbs help them to steer.A Sea lion has a small flattened tail in between its hind limbs. Sea lions have ear flaps. These animals can voluntarily open and close their nostrils. A common behavior of this animal is to scratch its neck with its hind leg like a dog. Sea lions rest in groups of ten or more on the beach. Their average lifespan is 15-25

They will say that it is immoral to kill any wildlife in general for any reason, but by not taking any action, these people will be indirectly killing bighorn sheep and cause the loss of an entire species of animals over just one individual mountain lion being killed each year. One single mountain lion being culled will have little to no effect on the overall population of mountain lions, but will significantly aid in helping the bighorn sheep species, all of which will die out soon if no action is taken. This method is supported by wildlife biologists as the most viable option for saving the sheep, so science should be the basis for the decisions made regarding Bill 560, not

Roar! Lions are very big. Males can grow up to be 10 feet long that’s a lot. The male lion is bigger than the female lion. The female lion can grow up to be 9 feet long. Males weigh from 330 to 550 pounds, which means they are heavy. Females weigh up to 265 to 395 pounds.

The sea lions currently populating the docks in Astoria Oregon may be causing serious depletion of fish as well as causing problems for the infrastructure of the docks they reside on. They are native to the California coastline but have made their way to the docks in Astoria which lies on the Columbia River. The reason this can be such a problem is because when you introduce an animal population that does not have any predators in their new habitat it can lead to overpopulation which leads to underpopulation of what they consume. In this case, the california sea lions are overpopulated and eating too many of the fish in that area of the Columbia River. The overpopulation of sea

The main reasons why sea lions are dying out is 1) domoic acid in algae called Pseudo Nitzschia is produced when the algae blooms. 2) The Blob or the El Nino is preventing the Upwelling, which brings in nutrients and nitrogen for the plankton. With the nitrogen not coming in, the plankton dies out. That causes the sardines and anchovies, who need the plankton to survive, to die out. Without the sardines and anchovies, the sea lions can’t

Majestic, noble, and brave, this famous iconic wild animal on the planet has captivated the people since the beginning of time. They are most feared by other animals thus, known as the king of the jungle – no other than the lions. Member of the genus Panthera, the lion is one of the big cats in the Felidae family. A lion’s head and body size average about 4.5 to 6.5 feet and tail of about 26 to 40 inches in length. A lion also weighs about 265 up to 420 pounds and a size relative to a 6-foot human. These mammals are also carnivores. Lions have always seen hunting in groups called pride. While lions generally avoid a full-grown elephant, lions still prefer their preys large like the zebras, buffaloes, and giraffes. Poised as the top animal in the ecological pyramid, lions have strong physical qualities, fascinating reputation, and an unfortunate decreasing number of population.
