Astroscopus (from Ancient Greek ἀστήρ (astḗr), meaning "star", and σκοπέω (skopéō), meaning "to look"), the electric stargazers, is a genus of stargazers, a type of percomorph fish from the family Uranoscopidae, part of the order Labriformes.[3] The species in this genus are anatomically distinct uranoscopids, being characterized by internal nares and being the only group of marine bony fish having organs which produce electricity which are derived from the extraocular muscles. They are found on the Atlantic and Pacific coasts of the Americas.[4]
