Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 6 - 7; Dorsal soft rays (total): 8 - 9; Anal spines: 1; Anal soft rays: 8 - 9. Characterized by semi-translucent pale grey body with 10 internal red bars; red head; first dorsal spine, slightly elongate; first three pelvic fin rays branched; fifth pelvic ray unbranched, 15% length of fourth ray; longitudinal scale series 23; predorsal scales absent; cheek and opercle without scales; depth of body 5.0 in SL (Ref. 90102).

Biology     Glossary (e.g. epibenthic)

Adults inhabit mainly oceanic drop-offs between 20 to 30 m (Ref. 38635). Also found in lagoons and outer reefs in 5-35 m (Ref. 90102). One of the smallest (=shortest) vertebrate of the world, with mature females reaching only 8-10 mm SL; scaleless (Ref. 9360).

Estimates based on models

Preferred temperature (Ref. 115969): 27.8 - 29, mean 28.2 (based on 10 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5078   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00708 (0.00333 - 0.01504), b=3.09 (2.92 - 3.26), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  2.9   ±0.3 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (tm < 1; Fec = 54;).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
