Biology

Behaviour & Diet

Feeding Strategy

Feeds on tiny benthic invertebrates, copepods and amphipods picked from rocky surfaces. Forages within a very small home range close to its shelter.

Micro-predator

Reproduction

Males guard eggs deposited on the underside of rocks or inside empty shells. The male fans the clutch to provide oxygen until the larvae hatch.

Nest guarder

Behaviour & Defence

Its small size and cryptic, pale colouration help it blend with rocky and sandy substrates. Retreats into narrow crevices when disturbed.
