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

They graze the Bahamas, Hawaii, Cuba, the Mediterranean, and any other warm waters.
The bull, shark known as Carcharimus Leucas, are widely cannibalistic. This means that they attack their prey when it is still alive. Also like both the great white and tiger shark, bull sharks hunt marine mammals. In Sharks and Other Dangerous Sea Creatures Idaz and Jerry Greenberg remark that bull sharks encounter a large number of people since they (bull sharks) inhabit fresh and salt water rivers and oceans. Bull sharks are found in the Pacific, Indian, and on both sides of the Atlantic Ocean. Bull sharks rarely are found far from the shore line. Bulls have traveled up the Mississippi, Zambezi, Amazon, Euphrates, and Tigris Rivers. The Greenbergs note that the bull shark was thought to being separate species until recently. In South Africa the bull shark is known as the Zambezi shark, one of the creatures that have been terrorizing the Natal Coast.
The Great White, Tiger, and Bull sharks are the greatest threat to mankind. I have told you what they feed on and where they are located. These are just the three most dangerous out of 250 species of sharks. Sharks are everywhere; you may be swimming with one every time you visit the beach without knowing it.

Sharks, the scariest, biggest, baddest creatures! That's what we make them out to be, but are they really? The answer is no, we say that. We kill more of them than they kill of us, about 900,094 more. Sharks, being carnivores, are NOT natural predators of humans.
Sharks have been creatures that can date back to over 450 billion years, and have survived through all disaster and still live on Earth today. This is a great feat for anything to stay in existence for that amount of time, and hopefully sharks can continue to live on this Earth and not go extinct. There are hundreds if not thousands of species of shark from when they first swam Earth’s oceans to when they continue to swim the same oceans. The study of sharks is a very interesting and extraordinary topic, being able to put together images of what sharks used to look like compared to sharks now is just amazing. In this vast amount of time sharks have spent on this Earth there has been many things that has changed, through evolution and adaptation. Through research and personal opinion I plan to show how sharks have evolved, what has changed through evolution and the history of
Sharks are aquatic creatures and very important to the living with lots of information humans may not understand. To start off, femeles give birth to 7-9 sharks per litter that are 3-4 feet at birth. Next humans believe all sharks are monsters but out of 400 species only 4 sharks have been claimed to attack on humans. Lastly sharks attack for 2 main reasons one reason is for defense and predation. They attack in defense when humans are in or around their territory they attack in predation mistaking people for seals. In conclusion sharks are creatures that humans are still learning about and try to understand them better.
Sharks grow slowly and reproduce at a low rate. Their natural rate of replenishment is low, because they reproduce late in life and produce few offspring (Sims and Reid, 2002). If too many of a certain shark species is killed in a certain area, it is possible that that species may never recover. For example, the number of dusky sharks and sandbar sharks off the eastern United States decreased by more than 80% between 1985 and 1995. The sand tiger shark and the great white shark are threatened world-wide. Despite reproduction, little is known about the status, behavior patterns, and their migration patterns of most
Sharks are the top predators. But frankly, they are starting to vanish out of oceans every day. The sharks biggest enemy are humans. Us humans will kill sharks for food. Sometimes people will even take shark teeth and turn them into jewelry. Humans also will cut off the shark’s skin, and turn it into leather. If you find that disturbing, did you know that some individuals will cut out the shark’s liver and make it into a type of medicine?
Sharks are one of the oceans top predators. They vary in size from the extremely small dwarf shark, to the colossal whale shark. Sharks can be found all across the world’s oceans, from the tropic waters of Hawaii to the sub zero temperatures in the Artic oceans. Of the hundreds of sharks a select few species have actually been recorded in the Artic. Of these few, only three of them spend the majority of their time in these harsh, freezing waters. These sharks are the Greenland, Pacific Sleeper, and Salmon sharks.
Many people call sharks beasts, terrible things, killers, but they are not. For instance sharks need to eat to just like humans. Sharks can eat all day. When sharks eat too much they throw it up and eat more. Sharks fend for themselves when they are hungry they might find other sharks and eat them. Sharks eat squid, shrimp, sardines, tuna. Besides sharks can never stop moving so they don't’ stay in one spot. Lastly sharks might look mean but they are
Sea Shepherd Conservation Society’s article “The Brutal Business of Shark Finning” reminds us that sharks play a key role in the ocean as both predators and scavengers.
The Discovery Channel has taught us that Great White Sharks are the largest predatory fish in the sea, and can eat something as big as a sea lion WHOLE. The biggest one was caught in 1993 off Prince Edward Island and was 20
Some people experience the scarier side of sharks, but throughout history it is a proven fact that beside four species of sharks; tiger, bull, oceanic white tip, and great white sharks, they are not killing machines. Their species however has been preyed upon for many years. The fear that is instilled within people shows up as the killing of millions of sharks to overcompensate. Thinking that if sharks were no longer around would somehow ease their fears.

The International Shark Attack File lists bull sharks as the species with the third-highest number of unprovoked shark attacks, with 100 unprovoked attacks (27 fatal) from 1580-2010.
There are over 400 different species of sharks. I am not going to list all 400 just the ones I find interesting. The bull shark is commonly found in warm shallow waters along the coast and rivers. Bull sharks are known for being aggressive. Bull sharks can live in both saltwater and fresh water.
In “What do you know about sharks?” by Sharon Guynup and “Great White Sharks” by Peter Benchley the clique thought of the “anthropophagous”, savage, and villainous shark is turned on its head. The two articles take widely accepted myths and debunk them with facts. Evidence that supports that the fish aren’t the vicious marine people-eaters that the media has depicted them as has been found. In this text the findings on the animal will be explored. This is the shark’s Real Bite.
Sharks are one of the most feared carnivores in the sea. There are 365 species of of sharks in the sea as we know today. All sharks are carnivores. Most of them eat live fish, including other sharks. A shark's most common natural enemy is an another shark. Most sharks eat their prey whole, or they tear off large chunks of the bodies. Some sharks crush their prey. Others take out small pieces off flesh from large fish. Sharks also feed on dead or dying animals. Sharks have the reputation of attacking human beings. But less than 100 shark attacks a year are reported throughout the world. Sharks are most common in warm seas and oceans. Whale sharks, are the largest shark known to man. Sharks are classified in the order
