Great White Sharks, Carcharodon carcharias, are the largest known predatory fish in the sea! The Great White belongs to the Family Lamnidae and are also known as the white pointer or the white death. The name "White Shark" is thought to have come from its universal all-white belly. According to the fossil record, the modern species have been around since roughly 18–12 million years ago. The most amazing hunters armed with strong muscles, good eyesight, and a keen sense of smell. According to (E. O. Wilson) "...rightfully been called a top carnivore, a killing machine, the last free predator of man—the most frightening animal on earth." First, Great white sharks have a conical snout, black eyes, a nearly equal-lobed tail fin, and that is supported on each side by a keel. Great white sharks are a gray and blue color on their dorsal fin. This is to help white sharks blend in with the bottom of the ocean when viewed from up top. The ventral, or belly, is white. This makes it hard to see sharks from above, especially when light shines in around them. The white shark has five pair of gill slits located in front of the broad pectoral fin. Great whites also have a …show more content…
They were long thought to be primarily coastal inhabitants, but from recent satellite tracking studies, we now know that they migrate long distances and they sometimes cross an entire ocean basins. Near the California coast, they can be found hunting elephant seals. On the western cape of South Africa, they can be found hunting for seals from May to September. In North American waters, great white sharks travel from the Newfoundland to Florida. They also travel from Aleutian Islands, Alaska to southern Mexico. They are found in all cold temperate and tropical waters, from 60°N latitude to 60°S latitude. Nowhere in its range is the white shark very common, and in fact, they are becoming increasingly
Before seeing this film and looking into it all I was aware of is what was shown on social media, which is what awful creatures sharks are supposed to be. Saveourseas.com had eye-opening statements comparable to the film. There were many persuasive arguments such as “Great white sharks, like all animals, are individuals with individual behaviors and characteristics. As the largest predatory fish, reaching six meters, they don’t have much to fear and are confident and curious animals.” This is a large point in both the documentary and paper. Since most people are constantly worried about how scary the animals are. It is hard for these creatures to get good publicity since our society is so judgmental and believes every detail the media puts out into the world. There are many points that focus on how hunting great whites is becoming more and more illegal, which is necessary for how important they are in the world. These sharks are able to help maintain a healthy balance in the
The bull shark may be known to thrive in the Mississippi River and around Nicaragua but are wide spread throughout the world. The bull sharks have an ability to penetrate far up bays and rivers. Some bull sharks have even been found as far as a couple hundred kilometers from the sea. Bull sharks have also been found in Potomac river. Potomac river is located in southern Maryland and is about 405 miles away from the ocean. There has never been a reported shark attack in Maryland which seems crazy now knowing that bull sharks have been found only 200 yards away from the point lookout state park in Maryland. What is crazy is that bull sharks have the abilities to travel in many different environments and depths but tends to stay in shallow waters between 3-30 meters of water.
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...
Seaworld is a giant marine life theme park. The greatest attraction to these many theme park would be those killer whales. In fact, these killer whales are the face of the park. As gigant as these mammals are, seaworld is keeping them in some pretty tight quarters. Mr. Jett and Mr.Ventre says “Wild killer whales can swim a hundred miles daily as they socialize, forage, communicate, and breed. In stark contrast, with little horizontal or vertical space in their enclosures, captive orcas swim only limited distances, with most spending many hours surface resting.” The animals don't have the freedom they need. Also when taking the whales out of their natural habit the whales tend to be depressed and not as heath in that situation. They need their freedom in the big ocean blue. Bring them into the small living units, breeding whales in captivity all for the entertainment of humans. At young ages the calves are taken away from their mothers on to a new seaworld park. Mothers of the calves have even been seen denying their offspring.

The great white shark is a very interesting animal. They get their names from their appearance. The great white shark is very big and has a blue stomach. The great white shark can be found in the pacific, Atlantic and Indian oceans. The number of great white sharks in the United States and in the world is unknown because it is too hard to keep track of all of them. They live in salt water and do not claim territories.
Shark nets have been implemented in locations across the world in response to shark sightings and attacks. Nets are submerged beneath the surface of the water, roughly 200 metres from the shoreline. The meshing is designed to be large to capture sharks, leaving them to struggle before eventually drowning under the weight of their own body. The meshing allows small fish to pass through, however captures larger fish and marine species. Shark nets provide no discrimination between common, vulnerable and endangered species, resulting in a high mortality rate for a variety of marine wildlife.
They like to be in deep water that is offshore in 43 to 62 degrees fahrenheit. When in cold water, they travel to inshore waters. They live from Aleutian from Alaska to the tip of Baja california in the eastern pacific ocean.
Mojetta wrote about prehistoric sharks, and the history of these creatures. According to Angelo Mojetta, author of Sharks, Cladoselache genus, one of the first prehistoric sharks, was buried in sediment that kept it preserved. Unlike other sharks, Cladoselache genus had a circle of tiny plates around it’s eyes for protection against it’s victim’s attempts to fight back. These sharks lived over 400 million years ago. Sharks of the past could mostly be identified by their teeth, because shark’s bodies are made of cartilage. Another shark that was focused on was called, Stethacanthus. This shark had a very unique look. Stethacanthus had a brush like decoration on the top of it’s head, and an extra fin like part that had the same bristle like decorations on it. These characteristics were thought to be used as suction cups, to hitch rides from larger fish. One of the most famous sharks that looks like an over...
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...
’’They are gray-brown to olive-green on top with off-white undersides,and they have heavily serrated,triangular teeth’’(National Geographic ‘’Hammerhead Sharks’’ 1).These are the usual colors of sharks. When you visualize a shark,the shark you would see would most likely resemble a bull shark. ’’They they almost resemble tiger sharks,and the problem is that tiger sharks are even more dangerous than bull sharks. To be honest,if you have to be extremely afraid of one species of shark,then it would probably be the bull shark. ’’Among the most likely sharks to attack humans,bull sharks favor shallow coastal waters-the same places humans prefer to swim’’(National Geographic ‘’Bull Shark’’ 1).This means that the bull shark would be the most feared by humans because they swim in the same places that humans swim.
On average they weigh 4,000-7,000 pounds and grow approximately 16-20 feet long ( Great white sharks 1). < commentary needed>Great Whites are the apex predator of the ocean containing 300 serrated teeth and highly-developed senses to hunt prey. Sharks have a great senses of smell, the Great White can smell a drop of blood thousand of miles away. They’re hearing is very powerful , being able to hear the vibrations of prey distances of about 800 ft away and find the exact location through ‘ear stone’( Great white 3). A shark 's sense of hearing truly shows their uniqueness as an apex predator. In addition to great hearing they’re known to have great sight by being able to see up to 50ft away and transition into seeing in light and dark. Additionally sharks have a lateral line on their back that reaches from the front to the back tail, allowing
They are creatures that have no clue what we are and are afraid of us. Every year, thousands of more people are killed by other people than by sharks; thousand more people are killed in car accidents than by sharks, and more people are killed by lightning strikes than by sharks. Each year humans kill tens of thousands of sharks, yet, there are fewer than 100 shark attacks upon humans. For example, The Great White shark also known as the man-eater, has the greatest reputation for attacking humans. Recent studies of Great Whites show that they mainly feed on sea-mammals. Seen from below the surface a person swimming with a shark looks much like a seal, with arms and legs sticking out. The shark usually surprises its victim, being a person or seal, by one massive bite, and then retreats in order to allow the victim to die before digesting the food. For this reason, many humans survived the attack of a Great White shark if they are saved before being eaten. Not only getting out of the water and be safe, but the result of loss, blood or
What is the largest fish in the world? The answer would be the Rhincodon typus, or commonly known as, the whale shark. The whale shark is vey unique because unlike normal sharks, the whale shark is a filter feeder and so, does not have use of its teeth. The whale shark is also about the size of a bus. However, like many animals in the world today, they are considered vulnerable according to the IUCN. They are seen often in the tropical areas, but many behavior and movement mechanism of the whale shark are still unknown.
With the addition of sharks anatomy, they have quite complex body parts than compared to simple bony fish, which can show a lot about the characteristics of sharks. Starting with gills, sharks "contain five to seven slits of gills on each side of their head" ("Shark Anatomy") all serving an important purpose for them to live. When the water goes through their gills the oxygen is absorbed by the blood in the gills and they move throughout towards the rest of the body. Since larger sharks contain more slits of gills for their bodies than compared to smaller sharks the body has to work less to oxidant the body. In the internal bodies, there are "electro receptive organs which are called Ampullaes, which are jelly-filled pores shaped like clay jars used by the Romans to ...
