Electro-Reception (Electric Sensitivity)

By

Definition:

Cartilaginous fishes like sharks and rays have an electro-receptor system, which is a finely-tuned sensitivity to electrical fields.

Sharks and rays have tiny pores on their skin that attach to long tubes containing a jelly-like fluid with a sensory nerve cell at the end, called ampullae of Lorenzini. These ampullae are sensitive to weak electric fields. All creatures produce an electrical field, and the ampullae of sharks and rays lets them pick up on this and find prey.
