The Blue-dashed rockskipper (Blenniella periophthalmus) is a saltwater fish of the family Blenniidae that grows up to 15 cm.
Description
The blue-dashed rockskipper is a small blenny from the Indo-Pacific. The species grows to about 15 cm and has a stocky, scaleless body with a blunt head, skin fringes above the eyes and fine blue dashes and spots; males colour up more brightly in the breeding season. As a dweller of the turbulent intertidal zone it clings to rocks and can jump among moist rocks. With its comb-like mouth it rasps algal mat from the reef bottom. The fish is harmless to humans. The IUCN has not evaluated the species.
