35. Blue shark

36. 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.

37. 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.)

38. 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.

39. Sharks can also sense electric and magnetic fields
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. 

40. More information What are Sharks? Males are called “Bulls” .
Females are called "Cows" .
Baby Sharks are called "Pups“.
