Short description Morphology | Morphometrics

Dorsal spines (total): 12 - 13; Anal spines: 2; Anal soft rays: 15 - 17; Vertebrae: 31 - 33. Dorsal fin XII or XIII (rarely XIII), 13-15, deeply incised between spinous and segmented-ray areas. Anal fin II,15-17. Pectoral fin 12-14 (rarely 12 or 14). Segmented caudal-fin rays 13. Vertebrae 10 + 21-23. Dentary incisor teeth which includes anterior canines very similar in appearance from incisors, 46-54 in males and 48 to 56 in females, averaging more in females than males; posterior canines 0 or 1 (usually 1). Lateral line without vertical pairs of pores, extending posteriorly to point between vertical from interspace between 9th and 10th spines and vertical from base of 11th dorsal-fin spine (rarely anterior to base of 10th spine). With cirrus on posterior rim of anterior nostril; absent on anterior rim. Posterior portion of body with sparse peppering of fine, dark spots (Ref. 5296).

Biology     Glossary (e.g. epibenthic)

Adults feed mainly on a diet of coral polyps and mucous (Ref. 94105). Oviparous. Eggs are demersal and adhesive (Ref. 205), and are attached to the substrate via a filamentous, adhesive pad or pedestal (Ref. 94114). Larvae are planktonic, often found in shallow, coastal waters (Ref. 94114).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Oviparous, distinct pairing (Ref. 205).

Estimates of some properties based on models

Preferred temperature (Ref. 115969): 24.7 - 28.4, mean 26.7 (based on 408 cells; Ref. 115970).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00741 (0.00328 - 0.01678), b=3.00 (2.81 - 3.19), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  2.0   ±0.00 se; Based on food items.
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low vulnerability (12 of 100) .
