Can sharks hear?
Sharks and other cartilaginous fishes are able to hear sounds in the water. They hear best in low frequency ranges below 1,000 Hz, the range of most of the natural sounds under water. No cartilaginous fishes are known to produce sound, as is the case in many bony fishes. A shark’s lateral line system, like that in other fishes, can detect nearby mechanical vibrations and sounds, as well.
