Short description Morphology | Morphometrics

Dorsal soft rays (total): 66-76; Anal soft rays: 50 - 61; Vertebrae: 40 - 44. The species is distinguished by the following: vertebrae 10-13 + 29-32 = 40-44, dorsal fin rays 66-76, anal fin rays 50-61, outer pseudoclasper spinelike with two distinct supporters, anterior being 1/2 length of posterior, posterior extruding; inner pseudoclasper slender consisting mainly of supporter which is about length of anterior supporter of outer pseudoclasper, directed backward; penis with abrupt change from a thick base to a thin outer part; opercular spine with a single, sharp tip; narrow scale patch on cheeks with 5-10 vertical scale rows; otolith very slender (length: height ratio 2.4-2.6); posterior mandibular pores are large (Ref. 57883).

Biology     Glossary (e.g. epibenthic)

Collected over sand, weed, and coral or rocky bottom; including tide pools. A 55 mm SL female (USNM 322029) specimen contained about 150 eggs about 0.5 mm in diameter and 19 embryos, 6-8 mm TL, with two rows of 9-11 small pigment spots along dorsal and anal fin bases (Ref. 57883).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00447 (0.00175 - 0.01142), b=3.10 (2.88 - 3.32), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.3   ±0.5 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low vulnerability (19 of 100) .
