Short description
Bestämningsnycklar | Morfologi | Morfometri
Mjukstrålar i ryggfenan (totalt) : 9 - 12; Mjukstrålar i analfenan: 9 - 11; Ryggkotor: 26 - 27. Distinguished from all other species of Aphanius by the following combination of characters: completely without scales; caudal fin slightly forked; males with dark pigmentation at the base of the four anterior dorsal rays; single row of tricuspid teeth with the two lateral cusps shorter than the middle one; rounded otolith with short rostrum and antirostrum of almost equal length; reduction in biomineralization of caudal skeleton such as thin epural bone; 157 (vs. A. dispar) and 170 (vs. A. ginaonis) molecular characters in the 12S mt-DNA and tRNA-Val (Ref. 96446).
Body shape (shape guide): fusiform / normal.
Inhabits rivers and springs that are often seasonal and characterized by shallow water and white layers of salt around and within the river. Often dominates on the riversides, where the water is shallow, warm and water flow is slow. Sympatric with Aphanius dispar (Ref. 96446).
