Description
The rippled rockskipper is a blenny of the family Blenniidae from the Indo-Pacific. The species grows to about 16 cm and has a scaleless body with fine wavy crossbars and small skin flaps above the eyes. It inhabits the intertidal zone of rocky shores, often among large rubble pieces that provide shelter at low tide.

With its rasping mouth it grazes benthic algae and growth. The species is harmless to humans.
