Amphibious behaviour and feeding ecology of the four-eyed blenny (Dialommus fuscus, Labrisomidae) in the intertidal zone of the island of Santa Cruz (Galapagos, Ecuador)

The labrisomid Dialommus fuscus, endemic to the Galapagos archipelago, is a predator of crustaceans, which moves up and down the intertidal zone with the tides. Its divided eye and elongated body permit it to Forage in the we t sections of the intertidal habitat during low tide. both on the rocks and below the water line and in tide pools. Compared with other intertidal fis hes (e.g. Bathygobius sp.). it was present on the rock flat in significantl y smaller tide pools nearer to the water line during low tide.
