Morphological study of goby (gobiidae) from Lombok Island – Indonesia

Abstract

Gobies (family Gobiidae) are bottom-dwelling fishes with flattened head, rounded snout, and bulbous cheeks that having a characteristic of two soft-spined dorsal fins and united ventral fins (disc-like) adapted to bottom-living life style. These modified fins are sucker device which enable the fish to grasp on surfaces and prevent from drifting in fast water current. Gobies are one of fish group who dominate ocean islands because of amphidromous larvae stage, euryhalinity, small size, an excellent climbing ability, a wide range of trophic level, frequent lack of gas bladder, and an associated bottom-living life style.
