Genus of fishes From Wikipedia, the free encyclopedia

Astroblepus is a genus of fish in the family Astroblepidae found in South America and Panama. This genus is the only member of its family.[1] These catfishes are primarily found in torrential streams in the Andean area.[1] Astroblepus pholeter and A. riberae are troglobites adapted to living in subterranean water systems.[2] These species are typically small, less than 10 cm (4 in).[1] The largest species reaches 30 cm (1 ft).[1] These fish have suckermouths like those of loricariids. They have two pairs of barbels, maxillary and nasal. The dorsal fin spine lacks a locking mechanism.[3] These fish also have odontodes, tiny teeth on their skin. All species exhibit a conical, pointy type on their fin rays like that found in other loricarioids; other species also exhibit a blunt type that is only found on their skin.[3]

Some of these fish are able to live in high altitude and climb the faces of waterfalls.[3] Their climbing ability comes from specially developed pelvic fins, as well as their suckermouths.[3] In their Neotropical Andean habitat, dry and wet seasons are quite extreme, and odontodes may help in sensing food, mates and water flow, as well as help cling to surfaces.[3] They feed upon invertebrates, such as caterpillars and annelids.[3]
The Astroblepidae were usually placed within Siluriformes as the sister family of Loricariidae,[4][5] but a recent study found them to be more closely related to the family Scoloplacidae.[6][7]
