About Gobies

Gobies (Family Gobidae), Including: Bigmouth sleeper or guavina (Gobiomorus dormitor); Sirajo goby (sicydium plumieri) Gobiidae or gobies is a family of bony fish in the order Gobiiformes, one of the largest fish families comprising over 2,000 species in more than 200 genera. Most of gobiid fish are relatively small, typically less than 10 cm (3.9 in) in length, and the family includes some of the smallest vertebrates in the world, such as Trimmatom nanus and Pandaka pygmaea. Trimmatom nanus are under 1 cm (3⁄8 in) long when fully grown, while the Pandaka pygmaea standard length is 9 mm (0.35 in), with a maximum known standard length of 11 mm (0.43 in). Some large gobies can reach over 30 cm (0.98 ft) in length, but that is exceptional. Generally, they are benthic or bottom-dwellers. Although few are important as food fish for humans, they are of great significance as prey species for other commercially important fish such as cod, haddock, sea bass and flatfish. Several gobiids are also of interest as aquarium fish, such as the dartfish of the genus Ptereleotris. Phylogenetic relationships of gobiids have been studied using molecular data. Fossils of gobiids date back to the Early Oligocene.
