The Northern Sea Lion, also known as the stellar sea lion, has the binomial nomenclature of Eumetopias jubatus. They received their name because the adult males have blubbery necks with long fur, like a lion. Their name basically means lion of the sea. These animals can be found in coastal waters of the North Pacific Ocean from Japan to central California. In the Western United States, there is estimated to be about 39,000-45,000 Sea Lions, and in the Eastern United States there is estimated to
Sea Lions: Nature's Playful Aquatic Land Mammals Introduction Sea lions may look like sea creatures, but they also behave like terrestrial animals. Unlike whales, mammals that spend their entire lives in water, sea lions inhabit both the water and land throughout their lives. This aquatic land animal prefers the water for food, fun, and safety; while preferring the land for socializing, territory, and procreation. Being mammals, they share many behaviors common to humans and other mammals
whales (Balaenoptera borealis) and sperm whales (Physeter macrocephalus) were exploited in an increased fashion after World War II (Springer et al., 2003). Whaling did not only affect whale populations, but it also affects populations of seals, sea lions, and sea otters. This is hypothesized to be the result of top-down forces from whaling, forcing great whales to shift their food sources to these smaller marine mammals. During the Second World War, whaling of great whales was at its peak. These whales
Sea Lions Sea lions are very social and super talented. They are true party animals, both on land and in the water. They can balance a ball on their nose, climb up a ladder, honk a horn and swim up to 13 mph. Kingdom – Animalia Phylum – Chordata Class – Mammalia Order – Carnivora Family – Otariidae Genus – Zalophus • External ears with flaps and big eyes. • Long flippers in the front which are like wings with no claws. • Five digits in the back limbs with extensions of cartilage. • Nails are on the
Today, in addition to the bottlenose dolphins, the Navy program includes sea lions and white beluga whales. The sea lions have excellent hearing and can dive much deeper than dolphins. They are trained for marking mines and retrieving torpedoes or practice mines, all while being more efficient than human divers. The white beluga whales dive deeper than the sea lions to recover inert torpedoes and are currently on loan from Sea World. Although it is remarkable that these marine mammals are capable of
seals, sea lions, otters, dolphins, and whales. Samuel Gruber in Discovering Sharks writes that the great white consumes marine mammals when they come across a deceased one. Even though the great white has the reputation of a man-eater; they attack thinking that the diver or surfers on a short board are part of its natural prey. The San Francisco area is known as the great white capital, because of the “Red Triangle.” The red triangle is the breeding ground for its natural prey, seals and sea lions
sun is beaming down and decide to go for a swim. As you approach the water, you see a whale unusually close. You begin to get nervous as it continues to approach the shore. However, you aren’t worried because you know that they are confined to the sea. As the whale comes near you can see it clearly. Just as you think that it will turn around, the whale walks out of the ocean! If you were to live during the tertiary period, this would be one of the things you would often see. All of the mammals
and watching our California Sea Lions frolic in the water, these all are some of the signs that are a constant reminder how blessed I am to be able to work
Can Marine Mammals Suffer From Decompression Sickness? Marine mammals are able to suffer from decompression sickness, which is a condition that occurs when sudden decompression causes nitrogen bubbles to form in the blood and tissues of the body. The lifestyles of marine mammals makes them susceptible to this condition, however, they have adapted to overcome this obstacle. Many marine mammals are capable of storing gas in their trachea during dives. The trachea is reinforced by cartilage, which
Research Paper Rough Draft If you’ve ever been to a national park, you will probably remember the experience for the rest of your life. But what is it that makes you remember that experience? Is it the sights, or the landmarks, or the history behind the park? Well I believe that Glacier Bay national park in Alaska is the most beautiful because of all of these reasons. The sights are breath taking; the tidewater glaciers are spectacular; and the history behind the park is intriguing. The Grand Canyon
Rosa. Santa Rosa is home to the island spotted skunk. Anacapa is located in Ventura county. Anacapa is five miles long. ¨The Anacapa lighthouse, turned on in 1932, was the last permanent lighthouse built on the West Coast.¨ Anacapa is home to thirty sea caves.

San Clemente is 56.81 square miles. San Clemente is
The first thing you should know is the physics behind a boat, seeing how you can't have a boating adventure without one. To keep it simple, let's check out the main thing you should know about a boat: Buoyancy. Buoyancy, by definition, is the upward force exerted by a liquid on any immersed object. If the force of the liquid on the object is greater than that of the object on the liquid then the object will float. In other words buoyancy is dependent upon the density of the liquid and the volume
entitled to a non-comparable killing-eating machine. This organism has become nature’s most genuine and most successful creature that it has remained unchanged for over 250 million years. Nature finally invented the perfect king of the sea. This animal has given the sea it’s “living” adjective; in turn, it was entitled—the “great white shark.” The Great White Shark derived from a series of evolutionary advancements that took several billion years. It began with the derivation of the vertebrates—the
Glacier Bay is located in the United States of America. More specifically, it’s in the southeastern region of Alaska, next to the Pacific Ocean. This 3.3 million acre National Park is one of the biggest features Alaska has. The history behind this Alaskan national park is interesting. In 1786, the first european arrived at the glacier region. His name is Jean-François de Galaup, comte de Lapérouse and he came across with Native Americans living there in Alaska. Later on, Russia declared the Alaskan
All animals are affected by climate change. One animal that is affected by climate change is the Spotted Seal or Phoca largha. They live in the Beaufort, Chukchi, Bering, and Okhotsk Seas. These are some of the world's smallest oceans they are the least known basins and bodies of water. This lack of knowledge about them results from their remoteness, hostile weather, and perennial or seasonal ice cover. However, this is Changing, because the Arctic may exhibit a strong response to global change and
Dear Mr. Curbelo, My name is Kylie Bennett. I believe we need to initiate a proposal to help our ocean environment. Plastic waste in our ocean is a huge problem. Everyday humans just dump tons of garbage into our ocean like the problem is just going to disappear. Well the problem is only growing more and more every time plastic gets made; it can take up to thousands of years for a pile of plastic to decay. The reported average lifespan of a plastic bag may be between 200 to 400 years. Plastic bottles
the primary producer (Mills et.al. 1993). Sea otters, which typically live in tidal areas off the western coasts of the United States and Alaska, are a common example of a widely studied keystone species. Sea otters, or Enhydra lutris, are keystone species to kelp forests because of their importance in maintaining the food web structure. They are top marine predators that are easy to observe because they live close to the shore (Laidre and Jameson 2006). Sea otters have low reproductive rates and have
