Gobiesociformes

Gobiesociformes is an order of ray-finned fish that includes the clingfishes. They are small, flattened fish with a distinctive sucker on their ventral surface, which allows them to adhere strongly to surfaces. Clingfishes are found in marine waters around the world, typically in intertidal and shallow-water environments. These fishes display a diverse range of ecological roles, including herbivory, carnivory, and even parasitism.

Common Names

Members of the Gobiesociformes are commonly known as clingfishes, but other names such as "sea snails" and "slippery dicks" are also used. The name "clingfish" is a direct reference to their characteristic ability to cling to surfaces using a specialized sucker.

Characteristics

Clingfishes exhibit a number of defining characteristics:

  • Sucker: A prominent adhesive sucker on the ventral surface, formed by the fusion of the pelvic fins. This allows them to attach firmly to rocks, seaweed, and other substrates.
  • Body Shape: Clingfishes typically have a flattened, oval-shaped body, with a compressed head and a small, terminal mouth.
  • Size: Most clingfishes are small, ranging from 1 to 15 centimeters in length.
  • Coloration: Clingfish colors vary, often camouflaging them with their environment. They can be brown, gray, or even brightly colored.
  • Fins: They have a dorsal fin, a caudal fin, and pectoral fins. The anal fin is small or absent.
  • Scales: Many clingfishes have a reduced number of scales or lack them entirely.

Environments

Clingfishes are primarily found in marine environments, with a strong affinity for intertidal and shallow-water habitats. They are commonly found in rocky shores, tide pools, seagrass beds, and coral reefs. Some species are known to inhabit deeper water, but the majority are found in coastal areas.
