Short description Κλείδες προσδιορισμού | Μορφολογία | Μορφομετρία

Ραχιαίες άκανθες (συνολικά) : 12; Μαλακές ραχιαίες ακτίνες (συνολικά) : 13; Εδρικές άκανθες: 2; Μαλακές εδρικές ακτίνες: 13 - 14. Body short, almost round. Color is brown with a black spot on the pectoral fin base. The caudal fin, caudal peduncle and the adjacent portion of the dorsal and anal fins white.

Adults inhabit inshore and offshore coral reefs. They are found in aggregations above corals (Ref. 9710). Benthopelagic (Ref. 58302). Oviparous, distinct pairing during breeding (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205).

Estimates based on models

Preferred temperature (Ref. 115969): 24.9 - 25.6, mean 25.3 (based on 35 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.02089 (0.00940 - 0.04644), b=2.98 (2.80 - 3.16), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Τροφικό Επίπεδο (Ref. 69278): 3.0 ±0.2 se; based on size and trophs of closest relatives

Ελαστικότητα (Ref. 120179): Υψηλό, ελάχιστος χρόνος για διπλασιασμό πληθυσμού < 15 μήνες (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).

Price category (Ref. 80766): Unknown.
