The Goby Fish

Fire Goby Fish

The Goby Fish is any of more than 800 species of fishes of the suborder Gobioidei (order Perciformes). Although several tropical species live in coral or in the cavities of living sponges, most gobies live in sand - or mud-bottom holes or burrows. During the spawning period the female goby attaches her eggs to an underwater object; they are guarded by the male until they have hatched.

Gobies are carnivorous, usually small in size, and found throughout the world. Especially abundant in the tropics, they are primarily marine in habit. Most species are bottom-dwellers and have a weak suction cup formed by the fusion of their pelvic fins.

The majority of species (more than 700) belong to the family Gobiidae.
These are typically elongated, sometimes scaleless fishes found along shores and among reefs in tropical and temperate seas. Among their characteristics are two dorsal fins, the first with several weak spines; lack of a lateral line (series of small sense organs along the head and sides); and, usually, a rounded tail. Many are brightly coloured, and some, such as the crystal goby (Crystallogobius nilssoni) of Europe, are transparent.

The pygmy goby is less than 1.3 cm (0.5 in) long. The sinarapan, only slightly larger than the pygmy, is regarded as a staple food of superior delicacy, with 454 g (16 oz) consisting of more than 30,000 fish. The mudskipper, sometimes called the skipping goby, is of Asian origin.

Most adult gobiids are 10 centimetres (4 inches) long or less; the Philippine Pandaka pygmaea, one of the the smallest living vertebrates, grows no longer than about 13 millimetres (3/8 inch).
Many gobies, such as the longjaw mudsucker (Gillichthys mirabilis) of the eastern Pacific, inhabit burrows in sand or mud, and some share burrows with other animals. An example of the latter is the blind goby (Typhlogobius californiensis), a small, pink fish native to California that lives in burrows dug by certain shrimp.

Another form of association between gobies and other animals is typified by the neon goby (Elecatinus oceanops), a small Caribbean species brilliantly banded with blue. It is one of several members of the genus that function as "cleaners," picking and eating the parasites from the bodies of larger fishes. The gobiids, like other members of the suborder, are egg-laying fishes and commonly guard their eggs, each of which is attached to a shell, rock, or other such site.
