These sharks have a very great sense of smell and sight. They have a limitless menu of diet items. Tiger sharks have sharp, greatly serrated teeth and extremely powerful jaws, this help them eat whatever they can find. These sharks are the top predators of the ocean ecosystem. Their prey would be overpopulated if the tiger shark was nonexistent.
“Orcas – intelligent, highly social, amazing,” the author claims, “beings – deserve their freedom.”(“The Case Against, par. 1). On the other hand, in the article “SeaWorld: The Truth...”, the main topic is showed in the second sentence of first paragraph. Moreover, throughout the article “The Case Against...”, the writer just focuses on the harms of captivity to the killer whales; on the contrary, “SeaWorld: The Truth...” talks about the park and people along with the orcas. For examples, SeaWorld is always the first in saving and protecting animals (“SeaWorld: The Truth...”, par.
With highly migratory species like bluefin tuna, management is complicated because these species migrate thousands of miles across oceans and international borders and are fished by many nations. Unfortunately humans are also hunting the majestic bluefin Tuna; not only are they being hunted but they are almost extinct due to the amount of human predation. Commercial fishing is the reason the bluefin Tuna is listed as critically endangered and needs to be conserved. There are some unique characteristics about this specific fish. The bluefin tuna are warm blooded, a rare trait among fish.
He is a consultant for Shark Defense. Shark Defense is a research company developing semiochemical, magnetic, and electrochemical repellents to reduce shark interactions.1 He says that you are more likely to be hit by lightning than to be attacked by a shark.2 Research says that you are more likely to drown in the ocean than to be eaten or killed by a shark. The sea itself is more dangerous that the sharks living in it. So why are people so afraid? Sharks often create images of strong teeth and huge long bodies swimming through the ocean looking for prey.
They have large mouths, and have nostrils near the front of the head. Their ears and eyes are located on the side of their heads. Sea cows live in the shallow warm water located in Western Australia. Western Australia ranges from Shark bay Marine Park all the way to Moreton Bay. The estimated population of sea cows is about 8000, and Shark Bay Marine Park has the grandest population of sea cows in the world with more than 1000 living in the bay.
While a large population of sea otters can wipe out abalone and crabs that fishermen make their living off of, otters were once heavily hunted for their fur. From over a million, otters have been reduced to less than a hundred thousand worldwide. Considered a threatened species, approximately 2,750 southern sea otters live in coastal California waters. Females weighing about forty five pounds outlive the males by up to five years with males living to be ten or fifteen. Mating season lasts throughout the year with a gestation period of six to eight months.
As if that was not horrible enough, dolphin trainers and veterinarians witness and sometimes assist the killings. If they see a "good-looking dolphin", they purchase them to use in dolphinariums (a dolphin aquarium) and amusement parks around the world (Brian Duignan, Dolphin Slaughter in Japan, Advocacy.britannica.com) including the beloved Sea World. A former Sea World biologist stated in a short documentary, "Sea World has been involved in illegal and unethical actions to assure their parks are well stocked with killer whales." He also said in the same documentary that, "Sea World representatives secretly promoted the Japanese dolphin drivers where thousands of animals are
Adult males have longer and thicker tails than females due to the fact that the male reproductive organ is located in the base of the tail. Green sea turtle - named from the green colour of the fat under its shell. Scientific Name: Chelonia mydas Sea turtles live on coastlines, islands, bays, protected shores, these are their main habitats. It is rare to see a sea turtle in the open ocean. Sea turtles prefer living in temperate and tropical waters and climate change is the cause for many sea turtle deaths.
Since turtles are too slow to catch most prey by all-out pursuit, questions about what turtles eat are quite common. The answer is that turtle eating habits are varied—what turtles eat depends on the available food sources, the habitat in which the turtle lives and the turtle's behavior. Most adult land turtles are plant eaters, also known as herbivores. They graze on grass or browse on the leaves of bushes and shrubs within their reach. Some turtles also eat fruits.
Like all animals, sharks are an important part of the ecosystem, without them the entire ecosystem will collapse. “Each year, up to 73 million sharks are killed for their fins, despite the fact that 30% of shark species are threatened or nearly threatened with extinction” (Krista Mahr). With fewer sharks existing in the ecosystem, their prey would multiply and become over populated and eventually wipe out other species. This occurrence will have an immense impact on many communities that rely on healthy fisheries. Shark poaching is a big concern because it affects the future of sharks and their place of living.
