Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 27 - 31.

Caught with dip-net or in surface plankton samples. Ovoviviparous (Ref. 205). The male carries the eggs in a brood pouch which is found under the tail (Ref. 205). Also found among Xenia soft coral in 1-10 m (Ref 90102).

Estimates based on models

Preferred temperature (Ref. 123201): 25.4 - 29.3, mean 28.4 °C (based on 1975 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00037 (0.00016 - 0.00085), b=3.18 (2.99 - 3.37), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.2 ±0.5 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).
