Although they have ears, many fish may not hear very well. Most fish have sensitive receptors that form the lateral line system, which detects gentle currents and vibrations, and senses the motion of nearby fish and prey. [1] Sharks can sense frequencies in the range of 25 to 50 Hz through their lateral line. [2]
Pores are concentrated in the skin around the snout and mouth of sharks and rays, as well as the anterior nasal flap, barbel, circumnarial fold and lower labial furrow. [10] Canal size typically corresponds to the body size of the animal but the number of ampullae remains the same. The canals of the ampullae of Lorenzini can be pored or non-pored.

The shortfin mako shark, the fastest shark and one of the fastest fish, can burst at speeds up to 50 kilometres per hour (31 mph). [87] The great white shark is also capable of speed bursts. These exceptions may be due to the warm-blooded, or homeothermic, nature of these sharks' physiology. Sharks can travel 70 to 80 km in a day. [88]
Among all sharks, white sharks have the largest reported olfactory bulb, making up 18% of their brain mass. It is said great white sharks can sniff out a single drop of blood in 10 billion water ...
The use of sight probably varies with species and water conditions. The shark's field of vision can swap between monocular and stereoscopic at any time. [58] A micro-spectrophotometry study of 17 species of shark found 10 had only rod photoreceptors and no cone cells in their retinas giving them good night vision while making them colourblind.
On "Superhuman Animals," Dr. Helen Czerski dove into shark-infested waters using only a certain smell as her defense. "Their noses are detecting the minute chemical cues I give off as I move ...
