Bellator egretta, the streamer searobin, is a species of marine ray-finned fish belonging to the family Triglidae, the sea robins. This fish is found in the western Atlantic Ocean.

Taxonomy
Bellator egretta was first formally described in 1896 as Prionotus egretta by the American ichthyologists George Brown Goode and Tarleton Hoffman Bean with the type locality given as off Barbados. The genus Bellator is one of 2 genera in the subfamily Prionotinae, one of 3 subfamilies in the family Triglidae, the sea robins and gurnards. The specific name egretta is the name of an avian genus, the egrets, and refers to the elongated ray in the dorsal fin of this species which resembles the long nuptial plumes of egrets.

Description
Bellator egretta has a many spines on its head with short spiny plates on the front of the snout have blunt spines and no large spines anteriorly, It has a small mouth which does not extend to below the eye. There is a sharp spine in front of the eye and large tentacles above the rear of the eyes, The nostrils are surrounded by spines and there are large spines on preoperculum and operculum, The cleithral spine is short, not extending beyond the large spine on the upper operculum. The first dorsal fin has 11 spines, with the first spine being elongated in males, extending beyond the caudal fin, and the second dorsal fin has 11 or 12 soft rays. The anal fin also has 11 or 12 rays, typically 11. The pectoral fins are short, containing 12 fin rays joined by the fin membrane and these fins reach just beyond the origin of the anal fin. There are 3 enlarged rays below the fin which are free of the fin membrane, the uppermost of these is shorter than the main part of the fin. There are no scales on the breast, on the membrane above the spine on the operculum or on the nape breast without scales.
