Why does sharks like the dark?
Sharks have a lateral line system along their sides, which detects water movements. This helps the shark find prey and navigate around other objects at night or when water visibility is poor. The lateral line system is made up of a network of fluid-filled canals beneath the shark's skin. Pressure waves in the ocean water around the shark vibrate this liquid. This, in turn is transmitted to jelly in the system, which transmits to the shark's nerve endings and the message is relayed to the brain.

How many people have been bitten by a staffordishire bull terrier?
This is a very difficult question to answer, simply because there are several breeds and crossbreeds which can fall into the category of Staffordshire bull terriers and this can create confusion. For example Pitt Bull terriers, American Staffordshire bull terriers and English Staffordshire bull terriers are three separate breeds, but would generally not be distinguished in reports if a dog has killed a human. Then there are also many crossbreeds who would also be classified as a Staffordshire bull terrier, but would not be a pure-bred one. Therefore, it is almost impossible to say how many people Staffordshire bull terriers have killed, but the number would be smaller than most people assume.
