Etymology: Cyprinodon: Latin, cyprinus = carp + Greek, odous = teeth (Ref. 45335); suavium: From the Latin suavium, meaning kiss, reflecting the distinctive protruded appearance of the lips.

Morphology | Morphometrics
soft rays: 10 - 11. Differs from all of its congeners by having a distinctive flattened and concave inter- and postorbital skull roof and thickened lips, with a terminal mouth opening. Lips are protruding by a stronger development of the underlying cutis connective tissue in the lip region (Ref. 55026).
Carnivorous, feeding on snails (Pyrgophorus coronatus), ostracodes and bivalves (Ref. 55026).
