Whale Fall Research Paper

The ancestors of the whales transitioned from being land bearing animals to becoming animals that live in the ocean. While the original ancestor of whales lived on land as it evolved it was able to start to enter the water until it struggled more to get on land than to get in water until the whale’s ancestors began to live exclusively underwater.

The evolutionary path of a whale is a fascinating process of a terrestrial mammal that evolves into a marine mammal. This evolutionary path started with one of the earliest ancestors called “Pakicetus”. A Pakicetus was discovered to be a land animal with four legs that had teeth as carnivores. It skull structure was long, but this organism didn’t look like any marine animal. The scientist then discovered that on the skull’s ear region it was surrounded by a bony wall. This feature on an organism only was distinct from one type of species, scientist discovered that this animal “Pakicetus” was an ancestor of a whale. By comparing the early whales Pakicetus to the next generation of ancestors Ambulocetus, the Ambulocetus whale looks more like

The origin of modern day whales, a mystery that has puzzled paleontologists for years, may have just been solved with the discovery of an ankle bone. This discovery might sound simple and unimportant, but the bones of these ancient animals hold many unanswered questions and provide solid proof of origin and behavior. The relationship between whales and other animals has proven to be difficult because whales are warm-blooded, like humans, yet they live in the sea. The fact that they are warm-blooded suggests that they are related to some type of land animal. However, the questions of exactly which animal, and how whales evolved from land to water, have remained unanswered until now.

There is no debate that one of the most attractive, human friendly and intelligent beauties in nature is the killer whale, more commonly known as the orca. The orca is in the dolphin family, but capable of learning human traits and freely interacting with them without causing any harm. Their curious behavior and acrobatic moves make us enjoy their company through watching and spending time in the waters with them. However, the gradual decline in the population of the orca is a worrying trend that sparks another kind of debate. Our interactions with killer whales is endangering their survival in the ecosystem, which should not be the case (BioExpedition 1). Our interaction with the

There is no doubt that humans have always been intrigued with the majestic beauty of the large giants found in all of the world’s oceans. Whales and people have had a long history together, marked by many turns of events.

Killer whales are one of the most fascinating displays of ocean life. The killer whale has characteristics that are important to its survival in the ocean. It is interesting to know that killer whales have a plentiful diet. It is astounding to see how killer whales behave in the ocean. I plan to tell you about the killer whale, its characteristics, its diet, and its behavior in the ocean as well as the predation of the orca.

Recent evidence suggests that whales may not have always inhabited the oceans. Bones of an ancient ancestor of modern day whales, the Basilosaurus, were discovered in Pakistan that suggest whales evolved from a wolf-like creature. This genus of an early whale lived 34-40 million years ago in the late Eocene. These fossils show many different features in common with both modern day whales and modern day land mammals. Since the discovery of these bones, many other evidences show that whales are a likely descendant of the Basilosaurus through many different ways, such as embryologic comparison and DNA testing. Whales aren’t the only suspected descendants

process. With the remaining dead whales, they cut them open and fill them with heavy objects to

Orcas are complex social creatures deserving freedom and respect, not captivity in theme parks under the guise of public education and entertainment. Aquarium staffs say captive whales are priceless educational tools. However, people can educate their children by bringing them to the wild instead of bringing the wild to them at the expense of the Orcas health and well-being. "The price of a family admission ticket is what continues to drive this cruel spectacle," according to Michael O' Sullivan, the Executive Director of The Humane Society of Canada (Whales in Captivity, 2010, Para. 3). Orcas suffer in many ways in

For years the killer whale, also known as Orcinus orca, has been drawing the attention of the public through the entertainment industry. These marine mammals have been bringing in billions of dollars to amusement parks such as Sea World, but at what cost? An idea that these killer whales can live happily and content while in captivity may be going through the minds of the public, but this cannot be further away from the truth. To have such complex creatures in captivity is not morally correct and there are many points against it, such as their level of emotional competence, violence between the killer whales, violence of killer of whales towards trainers, shorter lifespans, physical harm, and their level of intelligence. After taking a look at how these creatures function and the conditions they are put in while in captivity, there is no question about whether or not these mammals should be kept in captivity; an experience such as this affects these marine mammals just about the same as it would affect a human because of their high highly developed emotions and complexity. Since these industries do not have a natural authority over these creatures no matter the cause, the best thing they could do for these killer whales is to stop capturing them and return those who are capable back to the wild.

With success come some of the greatest stories of how people got to that spot. If you do try for something almost never will you be rewarded for that particular thing. This plays a role in both of the following books. In Whale Talk TJ must give this team and swimming his all to get what he wants in getting his team a varsity letter. When new requirements set back the team from getting their varsity letter TJ take it upon himself to lead and set an example for the rest of his team. Notably, in the book Summer Ball after Danny finds out about what people actually think about him. He takes accepts it and goes harder in camp. He takes nothing for granted anymore.

Whales are large aquatic mammals. Like every other animal they did not start off like that. Whales came to be after millions of years of evolution. Every aspect of the current whale was decided by nature. The blowhole, dorsal fins, lack of teeth and tail fluke all came from years of other creatures such as the Mesonychids and many other animals.

Sea lions and whales, Plesiosaur analogues, can endure environments which would kill a human. Humans are at risk of illness or death when returning from a great depth to the ocean's surface. Under pressure, nitrogen liquefies, or dissolves into the bloodstream, and an abrupt reduction in pressure can cause it to want to escape the body in the same way gases in a pressurised can wish to. Whales overcome this problem, because their rib cage and lungs collapse and compress under higher pressure: forcing the air into non-absorptive areas of the lung, and blood flow is reduced to the lung, reducing the intake of air and importantly, nitrogen:

Last Wednesday, July 8, beachgoers stumbled upon the carcass of a 2,000 pound beached whale on Long Island Beach. Since its discovery, experts from the Riverhead Foundation for Marine Research & Preservation who specialize in marine life have begun looking into the possible causes of death. The cause of the 12-foot minke whale’s death is being investigated because many wounds were present on its body, but it was unclear whether the bite-like wounds were inflicted before or after the creature’s death.

When the whales are exposed to a new pathogen, their bodies respond to it worse, which in many cases, lead to death.
