Alabes
Alabes is a genus of marine fish belonging to the family Pinguipedidae, commonly known as “clingfishes.” These fishes are characterized by their elongated, worm-like bodies and their ability to cling tightly to surfaces using their modified pelvic fins. They inhabit rocky reefs and tide pools in the Indo-Pacific region, often hiding under rocks or in crevices.
Common Names
Members of the genus Alabes are commonly known as "clingfishes," "wormfishes," or "snakefishes." They are also sometimes referred to as "blind clingfishes" due to their reduced eyes.
Characteristics
Alabes species are small fishes, typically reaching lengths of 5-15 cm. They have an elongated, cylindrical body that resembles a worm or snake. Their bodies are often covered in a layer of mucus, making them slippery and difficult to grasp. Their heads are small, with a terminal mouth and reduced eyes.
One of the most distinctive features of Alabes is their modified pelvic fins. These fins are located on the ventral surface of the body and are fused together to form a single, suction disc. This disc allows them to cling tightly to surfaces, even in strong currents. Their dorsal and anal fins are long and continuous, extending nearly the entire length of the body. They lack a caudal fin.
Environments
Alabes species are found in the Indo-Pacific region, ranging from the Red Sea and East Africa to Japan and Australia. They inhabit rocky reefs, tide pools, and other shallow water habitats. They are often found under rocks, in crevices, or among algae. They are primarily benthic feeders, using their mouths to pick up small invertebrates from the substrate.
