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.
For several years, Americans have been visiting amusement parks, like SeaWorld and Six Flags, to observe large animals like orcas, also known as killer whales. These whales are quite difficult to view in the wild, but can now be seen for a simple fee. Orcas are known to be one of the smartest mammals. They are friendly, and this has caused people to take advantage of them. For the past sixty years, people have brought these massive creatures into their aquariums to make a profit from their exhibitions. Often, without considering the orcas' quality of life. While kept in captivity, killer whales are forced to do many tricks they normally wouldn’t do in the wild. Over the years, there have been numerous controversies regarding killer whales
“… building a tank the size of Rhode Island wouldn’t be large enough for a six-ton male killer whale such as Tilikum, an animal capable of swimming 100 miles a day,” states an anonymous whale expert. Whales have been in captivity since 1861 when P.T. Barnum displayed the first live whale that was captured in Canada. However, Barnum had no idea how to care for the mammal and it died after only a week in captivity. (Animal Legal and Historical Center, 2014) Being up close with killer whales could give us some clues about how they interact with each other, including physical behavior, their dialect, and how their pods work together as a family unit. However, what we are finding is that whales who belong in the wild are suffering 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.
The ocean is a vast biome that is constantly changing. There is much to learn about the life within, the article “Omura's whales (Balaenoptera omurai) off northwest Madagascar: ecology, Behavior and conservation needs” showed how our knowledge of the ocean and the life within continues to grow. Balaenoptera omurai, or Omura's whale was only found as a new species in the year 2003. Their are no dependable population size estimates or evaluation of conservation facts because there is not enough data collected on these cetaceans. Scientists are able apply what they learn from some of these organism to humans. In the article “Reproductive Conflict and the Evolution of Menopause in Killer Whales” scientists were able to draw comparisons between Humans and other species.
Western Pacific whales are rather rare, with the California gray whale recently removed from the endangered list and the western Pacific whale having as few as 150 individual whales remaining rendering it critically endangered. A new study has emerged questioning whether western Pacific whales are really a separate population or simply California gray whales that have expanded their feeding grounds.
Sperm whales can hold their breath for over one hour because they have electrically charged proteins in their blood. The sperm whales make some of the longest dives of all the mammals in the whole world. Comparing the humans to the sperm whales, the longest time that in all time a human has ever held their breath underneath the water was for only 19 minutes and the maximum that a sperm whale can dive underneath the water is for 90 minutes approximately according to the scientists that study this whales. There is a difference of 71 minutes (1 hour and 11 minutes) between the time a human can dive into the water and the time a sperm whale can dive into the water.
Killer Whales are Large and intelligent animals that are kept in captivity. SeaWorld in San Diego has 23 killer whales in captivity. Marine biologist including SeaWorld critics agree that the whales probably will never be released to the open seas. How would you feel if you were separated from your family and never see them again? This is how the whales that are kept in captivity feel. Although some people think whales should be kept in captivity I disagree because this makes the whales unhealthy since they are living in a pool instead of the ocean.
At least 164 Orcas, Killer whales, have died in captivity all of them being premature deaths. Orcas should not have to suffer in captivity and should be left alone and stay in the wild. All Orcas in captivity will die at half there age. They must live in tiny tanks equaling to us living in a bathtub. They are captured from the wild when they are young and are taken from their family and then forced to interact with other whales from different whale pods which also speak a different language then them.
The second captive killer whale was in 1964. This eventually ended up as the first whale to be kept in captivity for a period of time. Today there are 52 killer whales in captivity that have great health and are with Sea World. Killer whales should stay in captivity because zoologists are finding better ways to help killer whale survival such as research and watching the things the orcas do. They are better taken care of and give zoologist and themselves the scientific benefits they need because scientists earn more information and the whales are provided with better health
The research shows that killer whales are not healthy in captivity. But we can stop this and seaworld has taken some steps to help solve the problem that orcas aren’t healthy in captivity. This problem affects the orcas big time, and the trainers that take care of them. Killer whales in the wild are having a great time, but remember in some countries there are no laws stopping them from catching or killing orcas. Maybe we should call them killer humans, instead of calling orcas killer whales because they’re really the problem. Research highly suggest that they expand their tanks or just plain out stop pulling killer whales out of the ocean. Some laws have been passed in the US to stop people from killing orcas or pulling them out of the ocean.
Killer whales were not considered a threat to humans until one day in February 1991. Keltie Byrne, a marine biology and former killer whale trainer was killed by Tilikum. According to the reports, she slipped from the tank, where Tilikum was located, prevented her from surfacing and killed her. Sadly, another tragedy of a trainer who was killed by someone she knows
Anyone who has been to SeaWorld or even watched an episode of National Geographic can appreciate the savage beauty and strength of Orcinus Orca, also known as the killer whale. This is the largest and smartest member of the dolphin family and can be found in all parts of the world. In the past twenty years, thanks to researchers like Ken Balcomb in Puget Sound, scientists have been making radical discoveries about killer whales (Martin, 1993, p.111-114). Modern research has shown the killer whale to be a highly perceptive, super articulate animal that has an amazingly complex social structure indicative of previously unrecognized intelligence.
Ever since the entertainment industry began to capture animals for the enjoyment of others, activists who believe animals can only subsist in the wild have been protesting against this monstrous act, using powerful propaganda to entice others to join their cause. The critically acclaimed film Blackfish, which highlights SeaWorld’s treatment of killer whales, apparently reveals shocking and appalling insight on accidental deaths caused by captive killer whales. One of the highest grossing documentaries of all time, as stated on director Gabriela Cowperthwaite’s website, Blackfish has captivated millions of viewers, causing them to reevaluate their values and advocating against SeaWorld. Although Cowperthwaite has stated in an interview that the “film is not at all advocating for anything,” and that she attempted to take a “journalistic approach” to documenting these phenomena, it is clear that the events depicted in the film reflect opposition to SeaWorld and its captivity of whales. Although Blackfish extensively applies human emotion and concepts to the animal kingdom to solicit sympathy from the viewers and provides misleading information to add to the sense of credibility, further research contradicts the points made in the film, rendering the conveyance of the film’s admonition against the captivity of killer whales ineffective.
In the mouth of a Baleen whale, hard plates of keratin grow down from the gums of the upper jaw. Keratin is the same protein our fingernails are made of. These plates are called baleen. They grow in rows on each side of the whale’s mouth.
