Short description
Κλείδες προσδιορισμού | Μορφολογία | Μορφομετρία
Ραχιαίες άκανθες (συνολικά) : 3; Μαλακές ραχιαίες ακτίνες (συνολικά) : 25; Εδρικές άκανθες: 3; Μαλακές εδρικές ακτίνες: 15; Σπόνδυλοι: 26. This species is distinguished from its congeners by the following characters: D III,25, all segmented rays are branched; A III,15 where anal-fin spines are moderately stout and pungent, the second spine stouter than third; scales in lateral series 37-38; circumpeduncular scales 16; predorsal scales 15, extending anteriorly to anterior AIO pores; caudal fin is rounded (Ref. 118103).
Water temperatures of two photograph sites were 18°C and 21°C , suggesting that this species is tolerant of relatively low temperatures (Ref. 118103).
