Astroblepus is a genus of fish in the family Astroblepidae found in South America and Panama.

[1] Astroblepus pholeter and A. riberae are troglobites adapted to living in subterranean water systems.

[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.
