Goblin Shark

Maggie Payne Per. 3 10/16/12 Final Draft intimately people probably think that sharks appe atomic number 18d around the same time as dinosaurs. But in fact they were alive roughly 132 million days before the dinosaurs. Even though sharks are older than humans, we soundless bop in truth elfin about them. The things we do be intimate are their structure, about species habitats, and what sharks are engagementd for by humans. The goblin shark is slightly assorted from different species such as the Great White shark or the Hammerhead shark. But in all sharks confine an queer skeleton, its odd because its made up of cartilage and its very flexible.Sharks besides take for slightly different organs from that of a human. For example, their stomach is very long, it stretches from the middle of their pectoral fin to the groundwork of their belly. They as well have gyrate shaped intestines, a large liver, and a small heart set(p) between the front of their pectoral fin and mo uth, bellow the gills. They also have small spikes coating their uncase called denticles. Sharks have the same five senses as humans do plus one extra sense. Sharks have very small holes around their head called ampullae of Lorenzini.These give sharks the world power to sense small electrical currents given come to by former(a) animals within one meter. Most sharks use this as an advantage man hunting while others dont need to. For example, they will use it while hunting for tilt hidden in the sand on the sea floor. Sharks are used for more things, which is causing them to become en dangered. Their strain is used for all sorts of food including, shark fin soup, fish and chips, smoked shark, canned shark and shark fish cakes, dog food, and sashimi.Most of them are caught off of Honshu, a main island of Japan, causing the various Japanese dishes. Sharks are also used for various medical reasons standardized cornea transplants. Heart disease medicament is made with chemicals ex tracted from shark blood, in that location are even shark cover tablets. Burnt angel shark skin was once used to direct skin disease, and cartilage is used to treat burns. Sharks are of ecstasy still hunted for their skin which is used for many things. For example, polished shark skin is used for purses, shoes, and to cover books and science tools.Shark skin was also used rural and with the denticles still on them, this is called Shagreen, which was used for non-stick grips and sword hilts. Also, shark teeth are often lay down and used to make jewelry such as necklaces. Although these things are good for humans, they are very bad for sharks because, they are fit endangered. Its bad because, if sharks went extinct, we would have a lot of big fish and seals to worry about because, they would be eating penguins and other birds that dwell climb water and they might even eventually become a danger for humans.Sadly, the goblin shark is probably one of the sharks that gets caught an d eaten. This would be an odd plentifulness too. Why? Well, the goblin shark has very flabby skin that is babble out gum pink with a blue tint on their fins. When they die, they snatch from that pink color to brown. They are generally about three to ten feet long but can grow up to thirteen feet long. They have an elongated snout which protrudes out of its forehead. It also has a long dope which looks similar to a frilled sharks tail.The goblin sharks underdress can extend out of their skull to the full length of their snout. Because of this, the prey rarely gets away, a nonher advantage that the goblin shark has on its prey is how its teeth are shaped. The teeth are long, dagger like, and smooth edged like, those of a Sandtiger shark. But the goblin sharks back teeth are flattened for curtailment things like shells. The teeth are probably like this because they feed on fish, cephalopods, and crustaceans such as crabs. They most likely feed on all these different things becau se of their habitat.They are scattered around the world and are found in the eastern and western Atlantic, specifically near French Guiana, the quest of Biscay, Madeira, Portugal, and atomic number 16 Africa. In the western Indian ocean near South Africa, and in the western Pacific, near Japan and Australia. They live about 40-280 meters down the stairs sea level which is near the bottom of the mesopelagic region of the ocean. They are at this depth because they like to be near the outer shelf and amphetamine slope area of the ocean. Most species of sharks like to be near, if not in, chromatic reefs like the Sandtiger shark.While others like to be in really deep water, like the pixie shark. Even though they like different depths of the ocean the Goblin and Sandtiger shark are very similar and from the same family, but the Goblin shark evolved before the Sandtiger shark. Despite how much we know about sharks, and how many species we have found, we actually know very little. We h ave actually hardly discovered about 400 species, most of which we know very little about. For example, we are still trying to understand and learn more about the expectant white sharks and they are one of the most well cognize species.We are still trying to learn more about them because there is a time in the year when they disappear for a short-change while. Scientists have guessed that its when they retreat to their breeding grounds. Humans even know a lot less about the goblin shark than the great white shark which means we have a lot to learn. specially since there are also a lot of different species of other sea life we havent discovered and we might not for a long while because we are unable to get to the bottom of the deepest trenches and have enough time to thoroughly search them.
