Short description
Κλείδες προσδιορισμού | Μορφολογία | Μορφομετρία
Ραχιαίες άκανθες (συνολικά) : 9. This species is redescribed and is distinguished from congeners by the absence of keel as the only diagnostic character; with lower number of dorsal spines 9 (vs. 10 in P. pungitius); head rounded with a concave snout (specimens longer than 35 mm SL) accentuating the impression of fleshy lips; dorsal spines 8-9; anal soft rays 7-11; scutes on the caudal peduncle 0-4; pectoral-fin rays 10-11. Colouration: body generally bright green with dark tints, covered by blackish blotches, which are absent on the pectoral and abdominal regions (Ref. 125067).
Adults inhabit shallow still water with dense vegetation. Feed predominantly on zooplankton, small crustaceans and benthic insects. Spawn for the first time at 1 year of age. Spawning takes place in April-June (Ref. 59043). Males build, guard and aerate the nest where the eggs are deposited (Ref. 205).
