Ecology Summary - Blenniella periophthalmus

Language:

Main Ref.	Sano, M., M. Shimizu and Y. Nose, 1984
Remarks	Oceanic (Ref. 61110). Found in coral reefs and rocky bottoms (Ref. 53568). Prefers clear, subtidal, fully marine waters near rocky or coral reefs (Ref. 9962). Inhabit exposed outer intertidal reef flats, where it can hide in cracks and holes. Commonly observed clinging to rocks as the water recedes below them during the low cycle of the swell and this species is often confused with mudskipper gobies (Ref. 48636). Feed on filamentous algae and associated small invertebrates, such as foraminiferans, ostracods, copepods, and gastropods (Ref. 205).
