Recommended: Few words on humpback whales
The decline of the dinosaurs brought the evolution of a new marine order know as Cetacea. Present day species of whales and dolphins began to emerge 10 million years ago. Of these 86 species that exist today, whales make up the majority of both the Odonotocetes and Mysticetes. These creatures are amongst the largest in the world and display an equally unique way of communicating with one another. Both baleen and toothed whales communicate utilizing sounds yet neither possess an external ear. Sounds are detected through a fatty structure that rests in between the middle ear and the mandible while the sounds given off to communicate vary between species, or in an orca's case, between pods. Mysticetes do not contain any vocal cords but instead have vocal folds that they communicate with and generate some of the most resounding biological sounds known to man. These series of clicks and moans come together as a whale song and is used to communicate anything from possible threats to identification of another whale to mating calls. Odonotocetes communicate a little differently by emitting high-pitched sounds and echoes to navigate themselves and determine the location of objects. Echolocation is imparative and provides a three dimensional view of the world below where only 1% of sunlight travels to 100 meters in depth. Migratory whales communicate through these methods across vast distances like 4,500 kilometers and continue to produce the same sounds between each other. Even when the slight changes between clans occur seasonally, the rest of the members in other breeding grounds follow suit. In 1996, when two individual Humpback whales ventured from the Indian Ocean to the Pacific ocean with their own unique song it was onl... ... middle of paper ... ...pollution. Natural causes include the avoidance of predators or weather conditions as well as the opportunity to chase prey or the unfortunate sickness of one whale in the pod. Pilot whales are often the victims of a mass stranding for a number of reasons. They are very social creatures, so if one member of the pod becomes sick and ventures ashore, the other will follow. This can be seen when recently, in Florida, approximately 50 pilot whales were beached, starting at a low number and steadily increasing with the screeches of communication between one another ( ). It is natural for one whale in a pod of pilot whale to follow another onto shore, being such gregarious creatures; however, the fact that they are deep sea whales emerging from great depths to beach themselves, is not a common feat. yet scientists are finding that it does in fact play a major role.
These killer whales are massive creatures living in these cramped pools not doing what they want to do when they want to do it. Mr. Jett and Mr. Ventre also said “...Typically spending their entire lives within tight family groupings, orcas captured from the wild, have been traumatically extracted from the security, comfort and mentoring which these groupings provide. Captured animals are confined to small, acoustically-dead, concrete enclosures where they must live in extremely close proximity to other whales with which they often share no ancestral, cultural or communication similarities.” Seaworld ends up throwing these animals in random groups of whales that are not their families, having whales that have never been outside of the concrete wall, to whales that all they know is the wild. The Documentary Blackfish states that one of the killer whale
Since whales are normally peaceful in the wild and they only seem to attack while in captivity, the argument is that captivity is wrong and dangerous for killer whales. This argument is supported by detailed facts about how the whales are tortured and agitated by other whales with no outlet. Both female and male whales are confined to a swimming pool where they are in a way being forced to try and mate. The female whales tend to abuse the male whales, which leads the whales to become mentally and physically unhealthy resulting in attacks on trainer. In the interviews with Corinne Cowell and Nadine Kallen, they mentioned that when they visited Sealand of the Pacific that three whales were confined to a “dingy pool”. Another appeal to pathos is when a neurologist that has studied killer whales mentions how the animals are very intelligent and are well-aware of what is going on around them. (SeaWorld) Killer whales have similar brains to humans, but have a bigger part of their brain where emotions are processed. With this, whales are more aware of their emotions and the bonds they make with humans and other animals. (SeaWorld) With the huge amount of raw footage, first-hand accounts, and true information, the film is able to grasp the attention of the viewers with the amount of emotion that is shown from the former trainers and the whales themselves. With these tactics, the film effectively appeals to the
Do you think the people of Sea Land and Sea World mentally injured the whales by taking them from their natural habitat? There were men sent on large sea boats and men in helicopters with some device that scans the water to locate the whales. Then once they track the whales they use the boats to separate the females and young ones from the males to try to abduct the youngest whales. People who cares about
For 50 years SeaWorld has entertained park guests with numerous stunts involving the majestic sea creature, the orca, also referred to as the killer whale, and their human trainers. What the on-lookers don’t see at these shows is what goes on behind the scenes: how the whales got there in the first place, and the conditions in which they are housed.
Today, we see much less of an obvious relationship of the cetaceans to the terrestrial mammals.
“… 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 captivity. Killer whales have no record of ever harming a human being in the wild. In captivity, there have been many incidents of killer whales harming or even killing their trainers. What would cause them to do this in captivity, but not in the wild? They have been known to resort to aggression toward themselves and each other, in what scientist believe to be a stress induced behavior. (Animal Legal and Historical Center, 2014) Evidence against having these wild animals in captivity is increasing and we need reevaluate the value of capturing and holding killer whales for our educational purposes, enjoyment, and profit.
Killer whales communicate by a series of clicks and whistles called vocalization. Each pod, or family, has their own unique language. This gives whales the ability to identify their own pods. Orcas have a brain that is about five ti...
These whale songs can be heard by humans because Humpback whales usually swim near the coast and sing with a strong voice. Whale songs can be heard in 30 kilometres’ distance.
In the front of the head is the melon. Its melon transmits sound waves that help it see at night to helping it catch its prey. Killer whales have sharp, cone-shaped teeth made for ripping and tearing prey. The Killer Whale has no sense of smell because there is a part of their brain missing that is missing. The sense of smell goes unused because they spend most of the time in the ocean. The blowhole helps the Killer Whale to breathe; the blowhole flap provides a watertight seal. To open its blowhole, a killer whale relaxes the muscle covering the hole (SeaWorld Parks & Entertainment).
Language is commonly held to be the province of humans, but other inhabitants of earth possess their own forms of communication. Birds, dolphins, and whales are some of those that have a language. Primates also use vocal communication with each other. Their utterances have varied uses and volumes, with each primate’s voice being distinct just as human voices are. These unique calls have given researchers insight into the social workings of primate groups. The very fact that primates have a language offers insight into the evolution of language and calls into question what the term human truly means.
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.
whales have surprised scientists not only because of their size and strength, but also because
Their beautiful song can travel miles and miles underwater. These sequences of moans, howls, cries, and other noises are quite complex and often continue for hours on end. It is most likely that humpbacks sing to communicate with others and to attract potential mates (National Geographic). Humpback whales travel in groups called pods. These whales, like others, regularly leap from the water, landing with a tremendous splash. Scientists aren’t sure if this breaching behavior serves some purpose. These whales are famous for the water acrobatics. Humpback whales can frequently be seen leaping out of the water and sometimes can use their flukes to propel themselves completely out of the water (Animal Planet).
These dolphins are the type of dolphins common people would see at the Zoo or on a T.V. programed performance. Like the Common Dolphins, the Atlantic Bottle-Nosed Dolphins are highly skillful echolocators. They can produce a range of sounds, like a click, using it to analyze any object around them in the ocean (Whitfield 114). According to Whitfield on page 114, they can produce up to 100 clicks a second. They will use these clicks to also find food. They mainly eat Bottom-dwelling fish in inshore waters or surface swimming fish. They can do many other objects with their echolocation finder and using their
