Short description
Κλείδες προσδιορισμού | Μορφολογία | Μορφομετρία
Ραχιαίες άκανθες (συνολικά) : 10; Μαλακές ραχιαίες ακτίνες (συνολικά) : 13; Εδρικές άκανθες: 3; Μαλακές εδρικές ακτίνες: 7.
Inhabits steep outer reef slopes exposed to strong currents where it lives in large gorgonians and black corals (Ref. 3921). Benthic (Ref. 58302). Common below 25 m (Ref. 90102). Feeds on small benthic or planktonic crustaceans. The suggestion that this species lays demersal eggs (Ref. 3921) is questionable. Pelagic spawning has been observed for this species from field observations (Ref. 26305). Monogamous (Ref. 52884), strongly territorial (Ref. 26305). Uncommon to rare in most areas (Ref. 9710).
Life cycle and mating behavior
Γεννητική Ωρίμανση | Αναπαραγωγή | Γεννοβολία | Αβγά | Γονιμότητα | Προνύμφες
Distinct pairing (Ref. 52884). Actual spawning lasts about 1-2 seconds while ascending a distance of less than 0.25 m (Ref. 26305). Courtship and spawning behavior is similar to that described for other species: 1) courtship commences just before or after sunset with spawning after sunset; 2) successive courtship and spawning by the male in social groups containing one or more females; 3) courtship and spawning at a site common to both male and female or at a site located within the female's home area; 4) pelagic spawning with a rapid but relatively short ascent into the water column by both male and female; 5) return of the male and female to resident corals afte spawning.
Monogamous mating is observed as both facultative and social (Ref. 52884).
