When many think of sharks, they think of the movie Jaws or a dangerous man-eating fish. In reality, sharks is a large group of fish that includes very small to much larger fish. Some can be harmful to man and others are harmless. To delve into this interesting and diverse group of cartilaginous saltwater fish that have sharp teeth and a bad reputation, ask your questions in this category.

Due to the fact that warmblooded animals use enzymes and energy from food in order to fluctuate between warm and cold temperatures, over-cooling rapidly can result in death, as can over-heating rapidly.
What is the most dagerous shark in the world?
The Carcharodon carcharias or the "White Shark" seems to be the most dangerous shark with 373 attacks.
Added by Sarahgtucker: the great white shark is assumed to be the most dangerous shark in the world due to all its bad publicity in the ocean and with Jaws. actually, the most dangerous shark is the bull shark often found in the Mississippi River, the Tennessee River, and the ocean will eat anything. it is the only shark that can live in fresh and salt water. the great white only attacks people when it is starving to death or thinks it is its food. the bull shark will eat anything no matter what it is.
What are behavioral traits of a shark?
Hope this Helps! White sharks' reputation as ferocious predators is well-earned, yet they are not (as was once believed) indiscriminate "eating machines". They typically hunt using an "ambush" technique, taking their prey by surprise from the bottom. Sometime they swim so fast that they actually jump out of the water while chasing/attacking seals. This is one of only a few sharks that can jump fully out of the water, the others are Thresher shark, Shortfin mako, Longfin mako, Spinner shark, Blacktip reef shark, Salmon shark, Porbeagle shark and the Copper shark. This is the only shark known to regularly lift its head above the sea surface to gaze at other objects such as prey; this is known as "spy-hopping", this behaviour have also been seen in at least one group of Blacktip reef sharks but this might be a behaviour learned from interaction with humans. It is theorized that the shark may also be able to smell better this way, since smells travel through air faster than through water.
More than any documented attack, Steven Spielberg's 1975 film Jaws provided the Great White with the image of a "man eater" in the public mind. While Great Whites have been responsible for occasional fatalities in humans, they typically do not target humans as prey: for example, in the Mediterranean Sea there were 31 confirmed attacks against humans in the last two centuries, only a small number of them deadly. Many incidents seem to be caused by the animals "test-biting" out of curiosity. Great White Sharks are known to perform test-biting with buoys, flotsam, and other unfamiliar objects as well, and might grab a human or a surfboard with their mouth (their only tactile organ) in order to determine what kind of object it might be.
Other incidents seem to be cases of mistaken identity, in which a shark ambushes a bather or surfer, usually from below, believing the silhouette it sees on the surface is a seal. Many attacks occur in waters with low visibility, or other situations in which the shark's senses are impaired. It has been speculated that the species typically does not like the taste of humans, or at least that the taste is unfamiliar.
Humans, in any case, are not healthy for Great White sharks to eat because the sharks' digestion is too slow to cope with the human body's high ratio of bone to muscle and fat. Accordingly, in most recorded attacks, Great Whites have broken off contact after the first bite. Fatalities are usually caused by loss of blood from the initial limb injury rather than from critical organ loss or from whole consumption.
Biologist Douglas Long writes that the Great White's "role as a menace is exaggerated; more people are killed in the U.S. each year by dogs than have been killed by White sharks in the last 100 years." [3]
Many "shark repellents" have been tested, some using scent, others using protective clothing, but to date the most effective is an electronic beacon worn by the diver/surfer that creates an electric field which disturbs the shark's sensitive electro-receptive sense, the Ampullae of Lorenzini. -Kiki
Some people use sharks for flip flops, food, fabric, and to keep them from eating people. All of this is wrong. I highly suggest not doing any of this.
