Cichlidae (Cichlids) > Geophaginae
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.
