The Family Gobiesocidae comprises a group of marine fish commonly referred to as clingfish. These fish are characterized by their adhesive disc-like suction cups located on their undersides, which allow them to cling firmly to rocks, algae, and other surfaces. Some of the synonyms for Family Gobiesocidae include clingfishes, suckerfishes, and rockfishes. With over 160 species of clingfishes distributed globally, they vary in size, coloration, and behavior. Most clingfishes are small and feed on invertebrates, while others can grow up to 30 centimeters in length and are considered predators of small fish and crustaceans. Family Gobiesocidae is an important group of fishes in marine ecology, and their unique adaptations have made them fascinating subjects of study for marine biologists.
