The Extinction of Fin Whale

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 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.

The dorsal fin is triangular, and has been know to grow in excess of 6 feet in length on males, but grow no more than 3 feet on females. (Martin) The pectoral fins of the orca can measure up to one sixth of it’s body length and is in the shape of a paddle. The orca usually have 40-50 conical teeth which measure over 2 inches in length, and has a perfect fit with the opposite set which makes it an excellent hunter. Although the teeth are robust, they do a lot of work through the years because older orcas have been known to have teeth worn down to the gum tissue (Haley.) The tongue of a killer whale has been known to weigh in excess of 2 tons (Martin.) They have been known to be fearless hunter, and a fast predator. Some say the ferocity of the killer whale exceeds that of the great white shark, which makes it one of the most feared in ocean life.

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

The debate surrounding Makah whaling is a heated one to say the least. There are valid points on both sides of the argument, but there is one side I find to be more valid once the facts have been looked at. I will examine and present my findings regarding past and current laws and regulations related to whaling, types of whaling, other countries that take an active part in whaling (and why), as well as the Makah culture – both past and present. In this paper I will argue why the Makah should not be allowed to resume whaling, as it is unnecessary and could potentially put the grey whale species back on the endangered list.

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.

The parties involved in this matter are the members of the tribe, both for and against the decision, the whales, the environmentalists, the courts that will settle the lawsuits and future generations that might be affected by any decision in regards to the impact on the whales sustainability. The decision at stake here is whether it is moral to revoke the ban and recent tradition,

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.

Holding killer whales in captivity is a harmful problem to the mammal that requires action from both the government and the public.

Despite the name given to these intelligent animals, killer whales don 't seem to be killer... in the wild anyways. Yet, places like SeaWorld seem to have shown people unintentionally that keeping whales in captivity and such small areas leads them to be aggressive, and essentially living up to their name. SeaWorld is an attraction that has been in the United States for many years, and although it provides great entertainment for individuals and their families, it also is a place where whales are treated poorly and held in captivity. While people enjoy the tricks the intelligent mammals are commanded to do, they don 't realize the poor conditions that they have once the show is over. Between whale fighting, poor feeding, and small areas; it is clear that keeping whales in captivity provides is both physically and mentally harmful to these animals. Many debates and arguments revolve around keeping whales in captivity, but keeping them in such small areas seems to cause them to lash out and hurt others. However, after learning about whales both in captivity as well as the wild, the realization that they should not be captive is starting to become noted by animal activists, the media and even the public. As the recent controversy of the poor conditions of killer whales in captivity is becoming more publicly noticed, animals activists are working towards the rights of killer whales.

Today, I will talk about the problem of keeping whales in captivity and how to overcome it.

In the 1800s the Northern Right Whales were killed mainly because their bodies have oily fat, which was used as a fuel at the time, they were also killed to make umbrellas, and whips (Endangered wildlife of the world). Other reasons for the Northern Right Whale being endangered is due to habitat pollution, Toxins, Climate and ecosystem change, Ruckus from whale-watching activities and noise from industrial activities. Also the death of the whales now is due to ship collisions and entanglement in fishing gear has limited the population’s recovery

Commercial whaling is a serious world issue that has always been difficult for those who are in support and those who are against it. Each group defends their side with convincing arguments. Morally, whaling is wrong, but do the reasons for whaling outweigh the reasons to cease the primitive hunts? By studying the effects of whaling,realizing how culture has changed over time, and taking note of the money that would be saved, it can clearly be seen that there is no longer a current need for whaling to continue. Efforts have been made to try to stop whaling, but with no help from any authoritative figure,nothing has been done to regulate the whaling. The famous sea shepherd, known for its strikes against whaling, can even be seen on

Whaling has become a global environmental issue as vast numbers of whales are killed commercially and scientifically every year. Intense debate on the necessity of whaling has been stirred but failed to be resolved due to the lacking of pragmatic measures employed by the responsible parties. Whaling nations continue to defend their whaling right for cultural and research purposes. Yet, ethical and humanity issues are among the controversial disputes raised by concerned public. In February 2010, International Whaling Commission (IWC) proposed a plan of lifting whaling ban by limiting scientific whaling activities with the intention of reducing overall number of whales killed besides solving the current impasse between pro
