Etymology: Medusablennius: Taken from Medusa, one of the three Gorgons, whose head with snakes turned him looked upon it into a stone + Greek, blennios = mucus (Ref. 45335); chani: Named for William L. Chan, the person who first noticed the distinctness of the species.
Eponymy: In Greek mythology, Medusa was a Gorgon whose hair was made up of living snakes. The name is used fancifully for taxa with numerous filaments or barbels. William L Chan was the first to notice the distinctness of this species (in a note in the jar containing the type specimens collected in 1955) which Springer examined (1963) at Stanford University’s George Vanderbilt Foundation collection.

Short description
Claves de identificación | Morfología | Morfometría
Espinas dorsales (total) : 11 - 12; Radios blandos dorsales (total) : 17 - 18; Espinas anales: 2; Radios blandos anales: 19. This species is distinguished by the following characters: no scales; 2 bones in the circumorbital ring, cirri on head numerous and complex; dorsal fin with more rays than spines; interopercle not extending posteriorly beyond its connection with the epihyal; ascending wing of the parasphenoid reaching the frontal; free dorsal margin to the upper lip; teeth restricted to a single series in each jaw, absent in vomer and palatines (Ref. 86957).
Body shape (shape guide): elongated; Cross section: oval.
Oviparous. Eggs are demersal and adhesive (Ref. 205), and are attached to the substrate via a filamentous, adhesive pad or pedestal (Ref. 94114). Larvae are planktonic, often found in shallow, coastal waters (Ref. 94114).
