A Killer Whale’s dorsal fin is located in the middle of their back and it does not have a bone, but instead is made up of tissue called collagen. It is a vital part of them because it helps them make sharp turns quick and allows them to ventilate the warm air and water away from their body when they swim to prevent themselves from overheating. The current tank sizes for most captive whales are around thirty-five feet deep and .0615 miles long which converts close to ninety-nine meters (Stowe). The tanks affect their fins because since they are so small the whales generally spend a lot more time breaching at the surface during training, shows, and free time. When the orcas do this it causes their fin to be exposed to the hot temperatures of the air for longer periods of times then they should.…
In the text, “What Do You Know About Sharks” is an informational text written by Sharon Guynup conveying many facts to the reader to give them more information about sharks. Sharks are species that produce children at an old age which is a problem society cannot fix. Nobody thinks “Hey! I’m killing a species that has a major role in the ecosystem! I shouldn’t do that!”.…
In 1975 director Steven Spielberg released the soon to be award winning movie Jaws. The adventure and also thriller movie cost eight million to make. Then racked up two hundred sixty million in the box office during its whole release in theatres. The inspiration for this movie, was brought from a real life story. When four people were killed by a great white in a sequence of attacks near the sea, in 1919, it was later caught and killed by two amateur fishermen.…
for example, “Sandbar Sharks move between the northeastern United States and the Yucatan Peninsula of Mexico, a distance of about 5,600 km (3,480 miles) (Helfman)”. Sharks will either cross oceans for migration or they will stick to the coast, but either way they can travel thousands of miles for migration. Vertical migrators do not travel great distances along coasts or across oceans like horizontal migrators, but more impressively, these migrators are experiencing a drastic change in temperatures and pressure. Vertical migrators dive down and resurface over hundreds of meters within a short amount of time, for example, “White Sharks may move up and down between the surface and 200-m (660-ft) depths as often as 96 times in 24 hours (Helfman).”…
Homeostasis is the action of maintaining a healthy internal environment. One example of homeostasis that we did in class is when we walked in place, causing our heart rate and breathing rate to increase while exercising to maintain a constant supply of oxygen. Another example from our reading is that sweating helps to maintain homeostasis by removing excess salt and opening pores to cool you down. It is important for organisms to maintain homeostasis because it assists the cells in the body to function and live.…
Stunning Spinners Spinner dolphins, which are mammals, are defined by a plethora of remarkable facts, and face an abundance of dangers. In addition, scientists have developed a fascinating method of taking samples of these dolphins. Out in the open ocean, spinner dolphins eat fish and squid, who live with them in tropical waters worldwide. Spinner dolphins can grow to be 1.8-2.1 meters or 6-7 feet long, and they weigh 55-75 kilograms or 121-165 pounds. Although a spinner dolphin’s life span is 35 years, not many dolphins live past childhood. Constantly puzzling scientists seems to be one of these dolphins’ many talents, for when attacked by sharks they refuse to retaliate in the slightest bit; they would rather become dinner.…
Science Paper Marine biologists study the behaviors of all marine organisms. They also have a lot of knowledge on all marine organisms. However, everything there is to know about the carnivorous great white sharks’ species hasn’t been discovered yet. Scientists can only do so much with these organisms in a controlled environment (or captivity) before an incident occurs where the shark either dies or puts others in danger. Erik Vance’s article, “Why Great White Sharks Are Still a Mystery to Us” provides examples of instances where great whites were put in captivity: “They refuse to live behind glass—in captivity some have starved themselves or slammed their heads against walls.…
Both the passage and the lecture are concerned with the decrease in sea otter population in areas of the Alaskan coast. The author of the passage claims that the decrease is due to pollution of the otters' environment. The professor refutes this point. He avers that the population decline originated in increased predator activity in these areas. First of all, the author points out that there are notable sources of pollution in Alaska, such as oil rigs.…
The Gopher Tortoise, also known as Gopherus Polyphemus, is a very important species in the ecological system of the state of Florida. The Gopher Tortoise plays a very big role as a native species in the south-east of the United States, from southern South Carolina to southeastern Louisiana (Auffenberg and Franz, 1982). More than 300 species benefit from the burrows the Gopher Tortoise digs, providing them with shelter. According to a study by Auffenberg and Franz (1982), Kushlan and Mazzotti (1984) and Diemer (1986), they prefer an open-canopied and spacious understory.…
Impact on the Ocean’s Ecosystem As sharks are commonly apex predators or tertiary consumers, the act of killing for shark fin soup has many ecological implications that can determine the health of the ocean’s ecosystem. Sharks provide many necessary behaviors and instincts that help maintain the ocean’s ecosystem. With this in mind, they have a large impact on the tropic levels of the ocean’s ecosystem as they have an adverse relationship with small species that help maintain the support the quality of the ocean water and a healthy living environment. Impact on Ocean Trophic Levels Sharks are indirectly correlated with coral reefs and the health of our waters. A decrease in their population would result in a hindrance of trophic levels, straining the overall health and regulation of the ocean ecosystem.…
Healthy oceans depend on shark populations to control other species’ populations and genetic diversity. The Earth Island Journal investigated current shark populations and determined that the ocean food web relies on shark populations to keep other species' populations (Shark 12). This event, known as trophic cascade, occurs when a top predator disappears from the food chain and the next trophic level (the animals the predators eat) overpopulate and eat all of their available prey and grasses. This leads to drastic problems within the ecosystem that take years to reverse. Additionally, Robert Days, zoologist at the University of Melbourne stated that if the shark population continued to shrink, their prey would overpopulate and eat larger…
During an emergency, it is possible for an organism to be placed on the endangered species list for a maximum of 240 days while the listing procedure occurs. Changes to the lists are proposed in a government…
They sometimes travel in groups called pods from cold water feeding grounds to warm water breeding grounds. The toothed whales travel in pods, but the baleens do not, they travel alone. The toothed whales travel in pods to catch prey and migrate together to share care of their young. Female whales usually give birth to one calf every 1-3 years in warm water. Even though the whales seem like they have a good life, there is always something threatening their existence.…
The Effects of Shark Finning An ecosystem is an environment in which a community of organisms live in. Our ecosystem is threatened by a numerous of things. If the ecosystem is put off balance or destroyed, it could disrupt the food chain and cause several shortages. The act of shark finning is one of these factors disrupting our ecosystem.…
What is the one of the most feared animals to roam the deep wide oceans? In case you did not know, the answer to that, it is the Great White Shark. Not only are they the most feared but they are also the most dangerous if mad. They can grow up to 20 ft long and weigh 5000 lbs. Their torpedo shaped bodies and very strong and powerful tails help this animal to reach up to almost 15 mph; which is very fast considering how heavy they are.…
