Short description Morfologia | Morfometria

Spine dorsali (totale): 6 - 7; Raggi dorsali molli (totale): 8-9; Spine anali 1; Raggi anali molli: 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).

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. 123201): 27.8 - 29, mean 28.2 °C (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

Resilienza (Ref. 120179): Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (tm < 1; Fec = 54;).

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