Sharks have six highly refined senses: smell, hearing, touch, taste, sight, and electromagnetism. These finely honed senses, along with a sleek, torpedo-shaped body, make most sharks highly skilled hunters. They often serve as top predators - keeping populations of prey species in check.
How many senses do sharks have?
Sharks have many obvious advantages over people in the water, especially when it comes to senses. In addition to those we have – sight, hearing, touch, smell and taste – sharks have two other senses, mediated by specialized receptors: electroreceptors and lateral lines.

SHARK SENSES
Sharks share our 5 general senses: sight, hearing, smell, taste and touch. They also have two additional senses that allow them to detect movement – the lateral line system and the ampullae of Lorenzini. SIGHT- The location of sharks' eyes on either side of the head allow for a wide field of vision.
Do sharks have a sixth sense?
Except they have a sixth sense, called the Ampullae of Lorenzini which are first described in 1678 by researcher Stephan Lorenzini. Sharks have a network of special cells that can detect electricity, called electroreceptors, in their heads. They use them together with the olfactory for hunting and navigation.

Do sharks have tongues?
Unlike other bigger fishes like dolphins that can stick their tongues out and make cute noises, sharks have what is known as basihyal. Shark's tongue is actually cartilage that is short, stout, very strong, but not flexible. It is located at the bottom of their mouth.

Sharks have only an inner ear, which consists of three chambers and an ear stone called an otolith. A shark's inner ear detects sound, acceleration, and gravity. Sharks use sound to locate food. Sound is often the first sense a shark relies on to detect prey.
Can sharks see below them?
Yes, sharks can see. However, tapetum lucidum is a special tissue present in sharks that makes it particularly adept at seeing under water. This tissue of mirrored crystals enables the animal to contract and dilate its pupil in much the same way as humans are able to. Other bony fish are not capable of this.

What sensory organs did the shark have?
Sharks have sensors that can pick up these electric signals using highly sophisticated sensory organs called Ampullae of Lorenzini. These sensory organs allow them to detect weak, low-frequency electrical fields given off by prey.
