Fin's Fish Guide
The Grotto goby (Speleogobius trigloides) is a saltwater fish of the family Gobiidae that grows up to 2 cm.
Mediterranean Sea, in shady underwater caves, overhangs and crevices of rocky shores from shallow to moderately deep water.
Description
The grotto goby is a minuscule goby of the family Gobiidae reaching about 2 cm, among the smallest fish in the Mediterranean. The translucent body is reddish and spotted; like other gobies the pelvic fins are fused into a sucking disc. As its name says, the species lives hidden in shaded submarine caves, overhangs and crevices of rocky shores, where little light penetrates. Among the rocks it searches for very small crustaceans and invertebrates. The male defends a crevice and guards the clutch in it until it hatches. Because of its minuscule size and hidden cave lifestyle it is rarely observed and was discovered only late; it has no fishery importance.
