It is absent in some species of shark, particularly fast swimming sharks. Shark Gill Slits Small pores on the head/body of the shark, which are connected to ampullae sacs which contain sensory cells connected to the brain. The ampullae sacs allow the shark to sense weak electric fields given off by other fish/mammals in the water.

Around a shark's head is an entire sensory network called the ampullae of Lorenzini, a very unique part of the shark anatomy. Each ampulla is composed of a cluster of sensory cells that ultimately enables sharks to detect prey that may be hiding in the sand, and even possibly notice changes in the water's temperature, pressure, salinity ...
