Intertidal, actively shuttling back and forth between rock pools and air (Ref. 31184). With acute vision to detect prey in the air (Ref. 94105). Treks on land as far as 30 m from the sea which it can remarkably carry on due to its physical adaptive modifications like, laterally flattened corneas to avoid myopia and thickening and filament enlargement of the gills for respiration out of water. Feeds on insects and shore crabs.
