Etymology: Aphia: Greek, aphia, -as = a kind of plant (Tussilago sp.) (Ref. 45335).
Environment / Climate / Range
Marine; brackish; pelagic-neritic; oceanodromous (Ref. 51243); depth range 0 - 97 m (Ref. 57814), usually 5 - 80 m (Ref. 57814). Subtropical; 13°C - 16°C (Ref. 57814); 70°N - 25°N, 13°W - 42°E
Length at first maturity / Size / Weight / Age
Maturity: Lm 3.8, range 3 - ? cm
Max length : 7.9 cm TL male/unsexed; (Ref. 26260); max. reported age: 1 years (Ref. 232)
(total): 4 - 6;
soft rays: 11 - 15. Transparent body, more or less reddish, with chromatophores along bases of median fins and on head. Vertebrae 26-28 (Ref. 232). Males with longer dorsal and anal fins than females (Ref. 35388).
Atlantic Ocean: Trondheim to Morocco. Also known from the Mediterranean including Black Sea and the Azov Sea (Ref. 57814).
A neotenic, pelagic species inhabiting inshore and estuarine waters, over sand, mud and eel-grass (Ref. 4343). Feed on zooplankton, especially copepods, cirripede larvae and mysids (Ref. 4343). Spawn in summer in empty bivalve shells (Ref. 35388). Probably migrate to deeper water to spawn during summer (Ref. 57814). Adults die after breeding (Ref. 4696) which does not qualify as a manifestation of semelparity but abbreviate iteroparity according to a recent study (Ref. 81039). Eggs are pear-shaped (Ref. 4696).
