Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 2; Dorsal soft rays (total): 22 - 24; Anal soft rays: 20 - 22; Vertebrae: 20. Diagnosis: Extremely small size at maturity (1.5 cm SL). Prominently elevated dorsal and ventral profiles. Extremely long bristles on caudal peduncle of male, projecting posteriorly to behind middle of caudal fin. Low fin ray counts (D.22 to 24; A.20 to 22; P.10) (Ref. 35708).

Inhabits sheltered coastal habitats, usually in areas with mixed low reef and sparse seagrass (Ref. 48637).

Estimates based on models

Preferred temperature (Ref. 123201): 25.2 - 29.3, mean 28.6 °C (based on 1897 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01995 (0.00943 - 0.04220), b=2.93 (2.75 - 3.11), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.0 ±0.4 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

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