| Remarks | 'preñadilla', i.e., 'little pregnant', is the local Ecuadorian name for this species and probably other Astroblepus species (family Astroblepidae) characteristic of high altitude streams of Peru, Ecuador and Colombia. In a lecture 1827-28, Alexander von Humboldt describes how preñadillas are washed down the mountains with landslides on volcanic slopes, to the locals more looking like the fishes coming out of the volcano itself (Sven Kullander, pers. comm.). |
