Краткое описание
определительные ключи | морфология | морфометрия
Distinguished uniquely from congeners in Europe by having a deep notch on the anterior margin of pelvic girdle. Differs further from other members of the genus by having the following combination of characters: trunk with 2-15 scutes; and scutes forming a lateral keel on caudal peduncle or keel absent. Morphological differences are reported in several lakes between individuals occurring in different substrates (mud, lava), especially in Lake Thingvalla (Ref. 59043).
Body shape (shape guide): fusiform / normal.
Adults inhabit streams and lakes (Ref. 59043). Males build, guard and aerate the nest where the eggs are deposited (Ref. 205).
