Great White Sharks Attacks Although sharks are often categorized as killers that hunt and eat as many humans as they can, this is factually inaccurate. Sharks very rarely kill humans. A person has a greater chance of being struck by lightning or drowning in a bath than of being killed by a shark. Only 74 people have been reported killed by great whites in the last century. But great white sharks can reach six meters in length and weigh 2,200 kilograms or more. With frightening jaws that can hold up to 3,000 teeth arranged in several rows, they could very easily kill and eat a helpless human in the water. Why is it, then, that most people survive attacks by great whites? Shark researchers are trying to comprehend the reasons that allow people to escape without being eaten. Great White Sharks Attacks

Hammerhead Sharks Pictures The hammerhead sharks are a group of sharks in the family Sphyrnidae, so named for the unusual and distinctive structure of their heads, which are flattened and laterally extended into a "hammer" shape called a "cephalofoil". Most hammerhead species are placed in the genus Sphyrna; some authorities place the winghead shark in its own genus, Eusphyra. Many, not necessarily mutually exclusive, functions have been proposed for the cephalofoil, including sensory reception, maneuvering, and prey manipulation. Hammerheads are found worldwide in warmer waters along coastlines and continental shelves. Unlike most sharks, hammerheads usually swim in schools. Some of these schools can be found near the Cocos Islands by Costa Rica. Hammerhead Sharks Pictures

Great White Sharks Teeth White sharks in certain areas have feeding times based on their ability to be camouflaged due to inadequate light. Shark attacks on prey usually take place when they are harder to detect. Early morning attacks are frequent. The strategy for procuring food is based on the size of the prey. Sharks generally do not like to expend too much energy in hunting. In some cases, one bite is sufficient to cripple a prey and allow it to bleed to death. If the prey is small, it may be ambushed from below and administered a death bite at the middle. Great White Sharks Teeth
