The ocean used to be a thriving community of billions of species. Bacteria, algae, plants, fish, animals, and many others have been living here. Unfortunately, over the years, this number has decreased drastically. Imagine the human species going down the Black Plague. Billions of people dying for what cause?
Whales in the wild live old and healthy to about the age of 30 - 60. In captivity, whales have a slim chance of that. Whales in captivity live 3 to 15 years. Clearly this is not right. I think whales in captivity should be banned.
However the expected lifespan of one is about 15 years. If the largemouth bass is in captivity, they usually get to be about 11 years old. (Boschung, et al., 2004) They usually prefer to live in shallow that is no deeper than three meters. Although sometimes you may find some of them living in the deeper part of the water. The largemouth bass have the ability to hide from their prey and provide protection against their predators through the process of abundant vegetation.

The Wood Turtle Keitan Chipperfield Have you ever seen a wood turtle? You might have, but I’m sure you probably didn’t see more than one or two of them. This is because this kind of turtle is endangered. This kind of turtle has been endangered for many years now. Ever since the ice age, the turtles’ population has been going down.
Many people may have seen the American reality TV show, "Whale Wars," it was broadcasted from the year 2008 to 2015. The show was about a group of activists' harassment and fight against the Japanese whaling ship. How the show depicted the fight between a group and Japanese ship was controversial, the show was cut off without a conclusion about this battle, but it concluded in me that the issue has to be ended without such fight. As a native Japanese myself, the Whale catching has been a controversial topic for decades, in particular, environmental activities against whaling increased rapidly since the 1980s and broadcasted or made the articles, the topic certainly caught the attention from worldwide. Japan adhere to 1946 International
From what scientists call the Carboniforous period sharks really branched out and took on different shapes and sizes with many different features in different species, this event is known as “The golden age of sharks” these sharks though, very different from the modern sharks that we find today. During the Jurassic periods sharks flourished and after this the diversification of the species was over and they barely changed for millions of years thereafter. Only when the huge meteor struck the earth were many of the shark species eliminated but few survived and still roam the oceans
In this respect, I will explain Linda Hogan’s book, People of the Whale, in the light of Christopher Manes’ article named “Nature and Silence.” Eight years have passed since the book named People of the Whale was written. In the meantime, the idea which is harshly criticized by the author is still a big question mark because the relationship between people and nature is getting worse each passing day. This book, which was published in 2008, narrates the story of Native American Thomas’ experiences both in his town and Vietnam War. The book which is based on environmentalist perspective successfully sheds light on the destructive side of the war as well. Historical Background Linda Hogan is Chickasaw, which raised her awareness in the migration problems such as the idea of melting pot.
Dolphins-World, a foundation whose goal is to raise awareness about dolphin captivity and inform people about dolphins in general, pointed out, “Orcas (Orcinus orca) and large sharks dispute the title of “The most dangerous predator of dolphins,” and is that both, with their size and other physical characteristics and, of course, their natural need to feed on meat, find dolphins attractive.” On the other hand, dolphins thrive in their natural environment and should not be kept in captivity for this reason. Maddalena Bearzi, a photo journalist and blogger, reported to National Geographic, “Dolphins, like some other animals, are essentially complex social mammals that need expansive space to live in. A tank can’t even begin to address these needs…” This data suggests that dolphins are very social animals that use a sizable amount of space and when they are being kept in small tanks, they are suffering from the need for more room to be able to do all the activities they would do in the wild. In one case, human interaction caused two dolphins to be captured illegally and sold to a hotel with a “swim with the dolphins” program. When the hotel no longer wanted them, the two dolphins were left to die in an aged and dirty tank.
During the late 1800s Sea Lions were hunted for their skins and meat which led to Sea Lions population to decrease dramatically then a law came out during the early 1900s to limit harvest of these animals so that they don 't become extinct. During the early years of the 1900s Japanese were killing Japanese Sea Lions for their meat to prevent starvation and used their blubber for oil to light their lamps and whiskers used for cleaning material in which their population was already low ranging from 30,000 to 50,000 then in which started leading to their endangerment and ultimately their extinction which came around the early 1950s which they presumed extinct after WWII due to the radiation the bombs gave off when the U.S dropped bombs on Japan. Going back to the sea lions ancestors it goes back to 32 million years ago and shows that Sea Lions were smaller in size like a sea otter and over those millions of years it 's gotten bigger and was close to a Walrus and was similar size but then later shrink down to the normal Sea Lion size we have today over the millions of years. Going through the Sea Lion species the steller Sea Lion during 1977 Steller Sea Lions where announced endangered due to a lot of the population suddenly disappearing to mysterious
The gray whale makes up one of around 80 known species of cetacea in existence today. 40. Because the gray whale is a marine mammal they are warm-blooded, breathe air, give birth and produce milk to feed their young. 41. The scientific name for the gray whale is, “Eschrichtius robustus”.
Polar Skuas usually live up to 11 years on the other hand an Albatross can live to about 50 years, but can live up to 80-85. The Snow Petrel have webbed feet that help them to swim swiftly and smoothly across large amounts of water looking for food. “Raptor of the South”, Albatross are known to be the most majestic of all the Antarctic birds with a total of 21 different breeds in the southern hemisphere. Albatross have a large head with a sharp hooked beak.The male Polar Skuas have a tendency to be smaller and lighter than female. For the migration the Polar Skuas will cross the equator and go into Alaska or the
Graph A represents recordings of a transient killer whale, whereas Graph B represents recordings of a resident killer whale. Both graphs show the changes in each whale type; one documents a drastic change over the course of four hours, while the other one—over the same amount of time—shows a more consistent pattern. A transient killer whale is represented in the first graph because, although a majority of the data shows the orca keeping to the higher points of the ocean, there are still points in which the orca dives to the bottom depth of the ocean, which would make sense due to the fact that this particular type of orca is known for preying on marine mammals. Based on the information in the chart, it could easily be assumed that they dwell closer to the top of the water, but when they are ready to feed, they dive to the
Lars Gustafson 11/4/15 GEOG 304 Research Paper: Shark Finning With an alarming one in four shark species endangered across the globe, we have come to a breaking point where our oceans ecosystems could suffer permanent damage if the practice of shark finning in the oceans off of Eastern Asia continues as shark population’s plummet. According to www.stopsharkfinning.net, tens of millions of sharks are killed every single year just for the fins that are the main ingredient in shark fin soup. Shark fins are harvested to feed the growing demand for shark fin soup that is an Asian delicacy food. When the sharks are finned they are usually thrown back into the water and left to drown slowly. Sharks rely on their fins to swim and allow water to
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.
