Etymology: Satanoperca: Taken from the prince of darkness. Hube liked to name cave fishes with diabolic names based on the idea of hell being underground + Greek, perke = perch (Ref. 45335).
Eponymy: Named after the devil, and referring in the case of the blindcat to the species’ underground habitat. Günther’s use of a name meaning ‘Satan perch’ for the cichlids was probably inspired by Heckel (q.v.) having named a species as ‘Geophagus daemon’. (Ref. 128868), visit book page.

Life cycle and mating behavior
Könsmognad | Reproduktion | Lek | Ägg | Fecundity | Larver
Ovophile mouth brooders. The parent fish clean the rocky substrate prior to spawning. Incubation takes place in the mouth. Juveniles use the mouth as their shelter for several weeks, where they attach themselves to the palate, by means of a specific gland (Ref. 35237).
