The Evolutionary History of Baleen Whales The baleen whale family houses the largest whales that are currently known to man, leaving many scientists questioning as to how, and why, these whales evolved to become so humungous, when millions of years ago they were much smaller. Questions as to how they evolved to only feed on minuscule prey are also raised when speaking about baleen whale evolution. The evolutionary history of these whales that caused their dramatic enlargement and the change in their prey, was triggered by several different factors: an ice age several million years ago and the seasonal availability of their prey. …show more content…

Why Is Tilikum To Blame?

505 Words | 3 Pages

Blackfish written by Gabriela Cowperthwaite. From the start attraction at Sealand of the Pacific in 1969, the aquarium grew attention for their orcas that would perform. Years later a two year old whale was captured and arrived in 81’. His name was Tilikum, coming in at two years old and 4,000 pounds. How do you go about taking orcas out of their setting, changing how they feel, and go about certain lies of how situations occurred?

Seaworld Research Paper

1047 Words | 5 Pages

Hannah Ton Mrs. Braun Honors American Literature 1 November 2015 SeaWorld Orca Breeding Should Not Be Continued When Dr. Heather Rally, a veterinarian who specializes with marine mammals, visited SeaWorld, she witnessed an orca with a severely collapsed fin and asked an “educational” guide why its fin was bent. The guide replied that it was a genetic trait just like curly or straight hair. However, Rally knows the truth, scientific evidence suggests that the high rate of dorsal fin collapse in captive orcas is due to conditions of captivity. These include spending an abnormally long time at the surface in direct sunlight and continuously swimming in tight circles.

Gray Whales Evolution

166 Words | 1 Pages

The invertebrates that form the gray whales primary prey are restricted to shallow water environments, but global sea-level changes during the Pleistocene eliminated or reduced this critical habitat multiple times. Because the fossil record of gray whales is coincident with the onset of Northern Hemisphere glaciation, gray whales survived these massive changes by adapting their feeding habits. When continental glaciers locked up vast quantities of the earth 's water, ocean levels dropped up to 400 feet. This transformed what is now the sea bottom into wind-scoured steppes. At the height of the ice age, most of the modern gray whale food source would have been high and dry, and yet, the whales survived.

Compare And Contrast Directional Selection And Disruptive Selection

732 Words | 3 Pages

Vertebrates are known to be animals with backbones. Tooth reduction is one of the major evolutionary trends that developed among major vertebrate groups that allowed for the transition from aquatic to terrestrial life. Evolution of limbs and being able to breath air are other evolutionary trends that took placeThese trends include improved respiration and protective and insulating body coverings. More over the transition from water to land also included changing to more efficient reproductive methods like having a placenta for some animals or egg layers for other animals. Lastly, the morphology of organisms evolved such that for land they would have paired, muscular appendages used for crawling and

Bering Strait Land Bridge Theory Of Early Native Americans

179 Words | 1 Pages

The Bering Strait did not provide much vegetation, which lead to less animals to be hunted. The early people had to make do with smaller mammals for food resources. It is theorized that larger mammals, such as wooly mammoths, would not be able to survive on the little vegetation that grew on the Bering Strait. Towards the end of the ice age the Bering Strait started to get smaller causing the few animals that

Killer Whales In Captivity Research Paper

1140 Words | 5 Pages

Andre Cole Ricardo Acosta G. English 101 September 22, 2015 Do Killer Whales Actually Belong in Captivity? Ever since wild animals such as Killer Whales have been captured and kept in theme parks and zoos as amusement, there have been issues on whether they should or shouldn’t be kept in captivity. Killer Whales, otherwise commonly referred to as Orcas, have regularly been taken away from the sea at a very young age so they can be trained, raised and kept in theme parks for exhibition. Although theme parks no longer capture whales from the wild, they are still bred in captivity for public display at marine parks such as Sea World (Gorman).

Sear Otters Analysis

In the other hand, the speaker contends this by explaining that whales were declined because of the human hunting , orcas changed their diet to survive and because just of the sea mammals were available, human started to hunt sea mammals and cause the decline. Third, the author asserts that scientist believed that the pollution hypothesis could also the uneven pattern of otters decline. However, the professor opposes this pint by explaining that the uneven pattern is better explained by orcas predation theory. she added that it depends on whether the location is accessible by orcas or not, so because orcas are large, they can 't access the shallow region where sea otters have not

Humpback Whales Research Paper

However, lack of information on past populations makes it difficult to compare the current recovery in this species, to that of pre-exploitation abundance. Estimates based on genetic diversity suggest they are still only a fraction of their pre-whaling numbers. The purpose of this paper is to examine the humpback whale’s role in the oceans, their populations, and the need for it’s conservation and the manor in which to do

Also, the lecturer argues that orcas are likely factors in the population decline of the sea otters because of the scarcity of their usual prepay. This left them with no other option but to hunt smaller mammals for food. The reading passage refutes this theory

Orinus Orca Research Paper

Territories border a specific species’ personal space, the Orinus orca is no stranger to this as any other living thing. What makes the whale’s reputation “killer” is its compliance to territories. Killer whales are innocent, but immature. Their actions prove them to be “killer” as witnesses say, but do they really think on the Orinus orca’s perception of the situations of violence they are involved in? Killer whale’s do what any other wild animal does, and when captive it is no surprise they would do the same.

Argumentative Essay On Dolphins

2117 Words | 9 Pages

The interactions between humans and dolphins started centuries ago when our ancestors carved drawings of cetaceans on rocks and passed on legends and folk tales; some described them as beasts and others as spiritual creatures. These marine mammals are also hunted as long as three thousand years ago as resources: their meat for food; their blubber for oil, and their teeth and bones for clothes, jewelry, or tools (Bauer, McCafferty, Simmonds, & Wright, 2013, p.201). As time pass, dolphin and whale hunting became a more prominent and structured industry, and the knowledge about these marine mammals’ biology and behaviors grew. In recent decades, with the help of ample media exposure and scientific publications, the public shifted its attitude
