Y'know the thing about a shark, he's got... lifeless eyes, black eyes, like a doll's eyes. From above, their grey backs help them blend in with the darker, deeper ocean waters below them. Sharks have a sixth senseHumans have 5 senses but sharks have a 6th electro-sense. 12.7.2019 12:00 PM. Sharks have ampullae of Lorenzini, sensory organs that allow them to sense the electric current of the heartbeats of their prey within a radius of 328 ft. (100 m). Source: qa.answers.com. If this movement stops, they suffocate. Some Sharks have three eyelids, an upper and lower one just like us. To learn more about the world of sharks, explore the links below.

Two small sensors in the skull allow the shark to zero in on the splashing sounds of a wounded seal or a fish. Why do white sharks roll back their eyes? Some sharks have a third lid known as a nictitating membrane, which will fully protect the eye. Great White Sharks lacks this membrane and therefore roll their pupils back in their heads for protection when feeding. They may use the surface kelp to disguise their silhouettes, making it difficult for sharks to detect and attack individual seals. ELECTRO-RECEPTION Sharks have a sense that humans can only be in awe of – they can sense an electrical field. The in a vertebra is made up of discs and strung like beads on the spinal cord. When he comes at ya, doesn't seem to be livin'... until he bites ya.
