The Common Shore-eel, scientifically known as Alabes dorsalis, is a species of clingfish found in the marine waters of the Indo-Pacific region. This relatively small fish, reaching a maximum size of 12.0 cm, is a common inhabitant of various marine zones, showcasing its adaptability to diverse underwater environments.
Description & Characteristics
The Alabes dorsalis is characterized by its elongated, eel-like body shape. Its head is relatively small, with a slightly upturned snout. Its dorsal fin is long and continuous, extending from the head to the tail. The pectoral fins are large and rounded, allowing for maneuverability. The ventral fins are modified into a suction disc, which enables the Alabes dorsalis to cling tightly to rocks and other surfaces. The color of this species can vary, often blending with the surrounding environment for camouflage, but typically exhibits shades of brown or grey, with lighter markings along the body.
Habitat and Occurrence
The Alabes dorsalis is primarily found in the Subtidal, sublittoral, infralittoral, deep zone of the oceans from the lower limit of the intertidal zone (intertidal) to the shelf edge at about 200 m water depth. neritic. This wide depth range reflects its ability to thrive in diverse underwater ecosystems, from the shallows to deeper regions. These zones encompass the areas where the Alabes dorsalis finds its preferred habitat, which includes rocky reefs, coral reefs, and seagrass meadows. The species can be found in both sheltered and exposed areas, highlighting its adaptability to various environmental conditions.
Taxonomy
The Alabes dorsalis species belongs to the Class: Teleostei, Order: Gobiesociformes, and Family: Gobiesocidae. This classification places it within the group of bony fishes, specifically the clingfish order, which is characterized by its suction disc-like ventral fins. The Gobiesocidae family includes a wide variety of clingfishes, all adapted to clinging to surfaces and utilizing a suction disc for movement and feeding.
Feeding
The Alabes dorsalis is an opportunistic feeder, mainly consuming small invertebrates and zoobenthos. Its diet includes a variety of organisms that reside on the seabed, such as crustaceans, worms, and mollusks. Its suction disc allows it to cling to surfaces and readily access these food sources, making it an efficient hunter in its chosen habitats.
