Sharks are fish that have been living around us 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 for 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 towards the ocean floor.The shark has senses specially adapted for the animal’s life underwater. Smell is a shark’s most acute sense. About 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 is, the less stimulant needed to elicit a reaction. Sharks are sensitive to light and can detect certain objects even in dark water. Just like cats and other animals whose eyes ‘glow in the dark’.Sharks do have ears. A shark can detect sound waves and disturbances in the water. Sharks can also sense electric and magnetic fields. Fast reading:1. Are sharks frightening?
