Short description Morphology | Morphometrics

Dorsal spines (total): 7; Dorsal soft rays (total): 10; Anal spines: 1; Anal soft rays: 9. This species is distinguished by the following characters: D VI + I,10; A I,9; pectoral-fin rays 12?14, the 2 upper rays with free tips; pelvic fins I,5, joined to form a disc which is emarginate (the shortest branches of fifth ray about 2/3?3/4 length of longest branches of fourth ray), no pelvic frenum; naked predorsal area and area at base of first dorsal fin; longitudinal scale series 26-29; transverse scale series counted forward 6-7, reaching naked area at first dorsal-fin base; transverse scale series counted backward 7-8; circumpeduncular scale rows 11-12; head with 7 transverse suborbital rows of sensory papillae; without tentacle above upper eye margin; anterior nostril is tubular, without flap at its tip, posterior nostril pore-like; semi-translucent body with small scattered orange-yellow spots and speckles, spots in predorsal area and a few midlaterally on body containing black dots; ventral part of body with a row of internal white spots above anal-fin base and on caudal peduncle; head and prepectoral area with small scattered orange to yellowish brown spots; first dorsal fin with 2 broad white bands at the base of fin and distally, middle of fin hyaline densely dotted with melanophores; colour of preserved specimen opaque white to yellowish with sparse melanophores (Ref. 116571).

Biology     Glossary (e.g. epibenthic)

This species were collected on a patch of rubble-sand bottom in less than one meter to 3 meters deep; found among shells sparsely covering the patch. More material and data are needed to check the relationship of this species to shells and their use as shelters (Ref. 116571).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5002   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00661 (0.00300 - 0.01455), b=3.08 (2.90 - 3.26), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.0   ±0.3 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 (10 of 100) .
