Dialommus fuscus Gilbert 1891

Spending as much as 50% of its time out of the water, after leaving the sea for the first time at about 2.6 cm, D. fuscus is capable of remaining out of the water for 20 minutes or more without wetting its gills (Ref. 28023).

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.

Dialommus fuscus, the Galápagos four-eyed blenny, is a species of labrisomid blenny endemic to the coasts of the Galapagos Islands. It inhabits the intertidal zone where it lives in tide pools as well as traveling on land. Special adaptations of the corneas of the eye and the gill filaments allow this species to travel up to 30 metres (98 ft) from the ocean in search of prey items such as insects and shore-dwelling crabs.
