Sharks can range anywhere from an average of 46 feet for the whale shark, to the most common shark, the great white shark at 23 feet, to the dwarf lantern shark, the smallest shark, coming in at a mere 6 inches ("What is the Biggest Shark" 1). There are approximately 400 to 500 species of sharks around the world. With so many species of sharks, one does not help but wonder if sharks really are dangerous or not. In fact, "Sharks have been said to eat almost anything. License plates, tires and whole cows have been found in the stomachs of a few" ("What Sharks Eat" 1). Of course along with those meals is the very few but once and a while, human bite. However, these menu items are not the normal everyday meal for sharks.
As a result of there being so many shark species, every shark has its own habits. This being they all have different food that they choose to eat, and different ways to eat this food ("What Sharks Eat" 1). Although they do all eat meat, and usually consume .5 and 3.0 percent of their body weight each meal. Unlike humans, sharks only eat about every two or three days, that is why they eat that much of their body weight with each meal. They eat anything from great white eating a sea mammal to a cookiecutter shark just eating a couple bites of their prey. Also, sharks play a part in survival of the fittest, to conserve their energy they often go after hurt or sick fish or mammals. Following what we learned in class, this allowed for the other prey to become stronger and healthier (Conger).
Mostly sharks eat fish, quid, and crustaceans. Although there are some that do have favorites besides these normal widely available food. The hammerhead like stingrays, smooth dogfish prefers crabs and lobsters, and tiger sharks eat sea turtles. Great whites, tiger sharks, and mako sharks all like to eat tuna, mackerel, and even other sharks. On the opposite side, some sharks, such as the whale shark, basking sharks, and megamouth sharks do not even hunt at all...
