Common Name: Goby, Gobioidei example: The Orange Diamond Sleeper Goby, Valenciennea puellaris
Currently more than 2,200 species of goby fish, suborder Gobioidei are defined.
Scientific Name: Gobioidei
Discoverer and date: Gobioidei Valenciennea puellaris Tomiyama, 1956
Where found: Gobiidae are spread all over the world in tropical and and subtropical or near tropical waters, nearly always near shore features. They are found in salt water, brackish, and freshwater areas. Gobies are almost always bottom-dwellers. They are often a third of the species found on coral reefs and a fifth of the diversity.
Description: The Orange diamond gobies are a beautiful, slender fish with a white body and orange markings. The top half of its body has orange dashes and spots, while a solid orange line runs horizontally along the bottom half of its body. Around its face, bright blue marks are also present. They can grow to six inches.
Many gobies have what is called gobiid morphologies, in which case the pelvic fins are fused to form a disc-shaped sucker. This anatomy is similar in function to the dorsal fin sucker seen in remoras or the pelvic fin sucker of the lumpsuckers. Since these are similarities but distinct from each to the other, they are seen as the independent development of similar features, called convergent evolution. Gobies can often be seen using the sucker to adhere to rocks and corals, and glass walls of aquariums. They are also often disturbing the sand or substrate leading to the toppling of rocks and corals.
