GOBIES - GOBIIDAE
Most are cryptic bottom dwelling carnivores of small benthic invertebrates; others are planktivores. Some the the very smallest fish species are gobies. Some species have symbiotic relationships with invertebrates (e.g. shrimps) and others are known to remove ecto-parasites from other fishes.
Typically nest spawners with non-spherical eggs guarded by the male.
Pelvic fins fused into an adhesive disc, when well developed. Spinous dorsal present or absent; when present with 2-8 flexible spines and discontinuous with soft dorsal. Cycloid or ctenoid scales almost always present. Prominent head barbels present in some species.
Latin, gobius = goby
