Info
Istiblennius spilotus is a demersal blenny fish that lives in tropical climates and is found on exposed rocky coasts, in tidal pools, and shallow surf zones.
Males can be recognized by a crest on their heads, which females do not have. The fish have dark, rounded spots on their bodies.
Males also grow slightly larger than females.
These harmless animals are herbivorous, although they also consume individual invertebrates.
In order to be able to graze on algae outside of the wet element in particular, Mother Nature has given these fish a special feature through evolution: they are facultative air breathers outside of the water.
Etymology:
The species name “spilotus” is derived from the Greek word “spilotos” (spotted) and refers to the small, bright white or blue spots on the head and body, especially in males.
