More information (http://new-brunswick. net /new bruns wick /shark/types. html)What are Sharks? Sharks are fish that have been around since the dinosaurs. Males are called “Bulls” .Females are called “Cows” .Baby Sharks are called “Pups”.

Other shark facts Sharks have five to seven gill slits. Many sharks must keep moving in order to breathe that is, in order to keep water moving past their gill slits but this is not true of all species.

Nurse sharks, for example, can lie still and fan their gills to bring oxygen-rich water across the slits. Because they lack a swim bladder, all sharks must swim in order to avoid sinking toward the ocean floor.

The shark has senses specially adapted for the animal's life underwater. Smell is a shark's most acute sense. Approximately 70 percent of the shark's brain is used for olfactory (smelling)  functions.

Experiments have shown that sharks can detect prey solely by smell, and the hungrier the shark, the less stimulant needed to elicit a reaction.

Sharks are sensitive to light and can detect certain objects even in murky water. Some have a tapetum lucidum, a mirror like layer under the retina of the eye that reflects incoming light and increases the amount of light available to the eye. (Cats and other animals whose eyes "glow in the dark" also have this feature.)

Sharks do have ears, but the role of hearing in the shark's location of prey is not well understood. A shark can detect sound waves and disturbances in the water with its lateral line, or lateralis, system.

This is a series of thin canals, filled with water, that runs along the animal's side. The canals are attached to nerves that send signals to the shark's brain.

Sharks can also sense electric and magnetic fields. Sensory pores located on the shark's head can detect a prey's bioelectric field even if the prey is buried in sand. A shark can also detect the Earth's magnetic field. Open-ocean sharks may use this information to navigate and orient themselves.
