Short description
Morfología | Morfometría
Disc broadly rounded. Upper surface of disk is pale and has dark spots. Ocellus on each pectoral fin usually oval. Ocelli are closer (Ref. 7251). Lower surface white without dark markings (Ref. 6902).
Benthic (Ref. 51024). Oviparous (Ref. 50449). Eggs have horn-like projections on the shell (Ref. 205).
Life cycle and mating behavior
