Morphology | Morphometrics
Distinguished from congeners in Europe by possessing two unique characters: 13-17 scutes on trunk, no scutes above anal base; and posterior edge of scutes smooth. Differs further by having scutes forming a lateral keel on caudal peduncle (Ref. 59043).
Europe: Extinct; formerly in Lake Techirghiol (south of Constanta), Romania.
Adults inhabit springs. Mature individuals spawn in February - October (Ref. 59043). Males build, guard and aerate the nest where the eggs are deposited (Ref. 205).
