SHARKS
There are more that 250 species of sharks, ranging from the harmless whale shark to the ferocious great white. I will describe the feeding habits and localities of the three greatly known to mankind: the great white shark (Carcharodon Carcharias), the tiger shark (Galeocerdo Cuvieri), and the bull shark (Carcharhinus Leucas).
The great white shark, known as Carchardon Carcharias, feeds regularly on marine mammals, such as seals, sea lions, otters, dolphins, and whales. Samuel Gruber in Discovering Sharks writes that the great white consumes marine mammals when they come across a deceased one. Even though the great white has the reputation of a man-eater; they attack thinking that the diver or surfers on a short board are part of its natural prey. The San Francisco area is known as the great white capital, because of the “Red Triangle.” The red triangle is the breeding ground for its natural prey, seals and sea lions. The triangle’s boundaries are north of Tamales Point, south of Monterey Bay, and west of the Farallon Islands, states Rodney Steel in the book Sharks of the World. The sharks also are found in quiet, shallow waters, along with in Australia.
The tiger shark, known as Galeocerdo Cuivieri, feeds regularly on marine mammals also. Tiger sharks do end up with curious articles in their stomach like license plates, lamps, and sheep. The tiger shark is a cannibalistic shark, which means it will attack its own kind when needed. Tiger sharks will feed on anything th...
The Great Shark debate – to cull or not to cull, has been at the forefront of the minds of conservationists, as well as the general population for many decades now. The opinions of everyone are divided, according to their personal experiences, and views on what is right and wrong for the environment.

But occasionally the younger sharks are preyed on by bigger sharks that do not necessarily have to be Bull sharks they can be become prey to any larger species of shark and occasionally a crocodile. However there are parasites like Pandarus sinuatus, and Periscopus dentatus that use the surface of the shark’s skin and use it to survive (Curtis). Though that does not in anyway decrease or increase the economic uses for the bull shark, its effects on the environment, or level of danger to humans. In certain places around the world the amount of bull sharks is decreasing slightly, because sharks can be harvested to make fish food, for their meat, for oils, and their fins for shark fin soup, or in asia their skin can be used to make “good leather” (“Bullshark”; Curtis). Even though their numbers are thought to be decreasing according to the International Shark Attack Files, otherwise known as the ISAF, has reported that there have been at least 70 reported unprovoked attacks on humans of which 17 were fatal, but that is only the known number of the reported attacks by bull sharks there most likely have been many more attacks that went unreported (“Bullshark”; Curtis). They are known for being one of “the most dangerous sharks in the world” because they along side the tiger shark,and great white they are the most common sharks to attack a human
The Carcharhinus leucas commonly called the "bull shark" is a very unique shark. The bull shark can live in both salt water and fresh water but is commonly found along the Mississippi River and around Nicaragua. The bull sharks has a very blunt rounded nose giving it a bullish type of appearance thus giving it the name bull shark. The sharks are a dark black to a light grey with a white underbelly. Bull sharks can grow to be about 350 cm long and weigh around 230 kilograms. Bull sharks also tend to have smaller eyes compared to many other sharks which indicates that the bull sharks have limited vision. The bull sharks have triangular teeth like the great white shark (one of the bull sharks cousins). The bulls teeth are heavily serrated and are about 1.5 inches long which makes it easy to tear apart the flesh of their prey.
This image is what a majority of people believe to be the shark. They believe it to be the bloodthirsty sea monster that appears in countless works of literature and films, but science says otherwise. The classic picture painted by the minds of sailors returning from years at sea come from imagination and sharks’ violent methods of hunting and mating. Sharks fear humans as much as humans fear sharks, and most sharks, particularly the “man-eating” great whites, only bite humans because they mistake surfers for seals. In earlier times, the ocean was a source of mystery and adventur...

The Swell Shark, whose scientific name is Cephaloscyllium Ventriosum, is swell. The Swell Shark has many unique features, including its habitat, anatomy, feeding, and defense tactics. The Swell Shark is also a member of many diverse taxonomic groups, including Chordata and Chondrichthyes. These groups have many defining characteristics, which the Swell Shark displays all of. Lastly, despite the Swell Shark being of Least Concern in terms of conservation, it is still important to protect this species.
In Chinese tradition, Shark fin soup is called as “a celebration soup”, which people eat it to celebrate in various occasions. Moreover, people also believed that shark fin consisted of diverse nutrition values which provide them virility, wealth, and power(Wolchover, 2011). These beliefs lead to the beginning of poaching for sharks, the top of food chain in the sea world. Surprisingly, although people are aware of the decreasing number of sharks since the old days, around hundred million of sharks are still hunted each year(Heltus, 2013), to be served on luxury tables surrounded by those believers in things that they do not even prove whether the belief is reliable. Therefore, in the generation that people are mostly educated, sharks should no longer have to be continuously killed for their fins.
Well if you happen to have no idea or clue as into what I’m talking about, which I seriously doubt that’s would be the case. Ever saw the movie Jaws and all of the subsequent directed by Steven Spielberg, then you definitely have a great picture of what the Great Whites are and what they are capable of doing to a human and other sea animal, this also label them one of the most dangerous wild life. The Great White also goes by these other names White Pointer or White Death is from a large species of lamniform shark. If you ever trying to locate on...
In 2015 only 59 shark attacks have occurred around the world compared to the millions of sharks killed by humans every year. Due to these accidental shark attacks people tend to think that sharks, especially Great Whites are evil creatures with malice intentions when attacks do occur; but, on the contrary that is wrong. Sharks are not the only beautiful and unique creatures in the ocean, they also play a vital role in our ecosystem; however, due to human interference they might not be around much longer, through awareness sharks can be protected from endangerment.
Thesis: Sharks should be conserved because they are an important part of the ocean, attacks are often incidental, and human behavior influences the behavior of sharks.
Most people think that sharks are large, fast-swimmers, and savage predators. This is true of some species and groups should be interested of the appealing aspects of biology found within it: all sharks have an excellent sense of smell; some can detect electrical discharges; some sharks give birth to one of the
The morphology of whale sharks is mostly similar to aquatic fish species, but many specific traits help differentiate them from the rest. Whale sharks are the largest fish in the world and can reach a size of around 20 meters (Martins, C., and C. Knickle). This is often compared to the size of a school bus. The shark has a very large transverse mouth. They have 5 very large gill slits and have a larger first dorsal fin compared to the second one (Whale Shark). They have a distinctive spotted “checkerboard” pattern with stripes (Martins, C., and C. Knickle). It is not exactly known why they have this specific body marking. It is believed that the body markings act as a camouflage. The strange thing about whale sharks is that they have 300 rows of teeth that play no role in feeding (Martins, C., and C. Knickle).
