Clingfishes are fishes of the family Gobiesocidae, belonging to the order Gobiesociformes. They are widespread throughout tropical and warm temperate waters, particularly in the marine waters of the Atlantic, Pacific and Indian Oceans. Most species shelter in shallow seagrass beds and reefs, clinging to rocks, algae and seagrass leaves. Some species shelter in sea urchins or crinoids, or cling onto the bodies of larger fish.
