Kurzbeschreibung Morphologie | Morphometrie

Rückenflossenweichstrahlen (insgesamt): 66-72; Afterflossenweichstrahlen: 53 - 57; Wirbelzahl: 40 - 41. The species is distinguished by the following characters: very small eyes (1.1-1.6% SL in diameter); no upper preopercular pore; robust head, length 27.0-29.6%SL); narrow scale band on cheek with 1-2 scale rows on lower par; anterior inner pseudoclasper submerged in pocket of isthmus; otolith with fused colliculi (Ref. 55786).

The minute eyes are indicative that it could be a cave species, but so far collected only on coral reefs. A 31 mm SL female was found with a 3.7 mm long bilobed ovary containing 50 eggs, with 0.4 mm diameter (Ref. 55786).

Estimates based on models

Preferred temperature (Ref. 123201): 27.4 - 28.2, mean 27.9 °C (based on 164 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.2 ±0.5 se; based on size and trophs of closest relatives

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