Etymology: Proterorhinus: Greek, proteros = former + Greek, rhinos = nose (Ref. 45335).
Name should be changed to Proterorhinus semilunaris Heckel 1837 according to: Stepien C.A. & M.A. Tumeo, 2006: Invasion Genetics of Ponto-Caspian Gobies in the Great Lakes: A ‘Cryptic’ Species, Absence of Founder Effects, and Comparative Risk Analy
Environment: milieu / climate zone / depth range / distribution range
Marine; freshwater; brackish; demersal; pH range: 7.0 - 7.5; dH range: 10 - ?; amphidromous (Ref. 46888). Temperate; 4°C - 18°C (Ref. 2060); 60°N - 36°N, 17°E - 54°E

Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 11.5 cm TL male/unsexed; (Ref. 2058)
(total): 7 - 8;
soft rays: 12 - 15. Seven transverse suborbital rows, complete oculoscapular and preopercular lateral-line canals, scaled nape and as a distinctive autapomorphy, an elongate anterior nostril, which extends over the upper lip. Broad dark oblique banding across the body.
Pure inhabitant of brackish waters (Ref. 92840). Occur in rivers and estuaries (Ref. 4696). Based on morphological and molecular data, this species does not enter pure freshwater and inhabits brackish waters in Sevastopol, Crimea (Ref. 59043).
