Etymology: Acentrophryne: Greek, 'a' = without + Greek, 'kentron' = prickle or spine + Greek, 'phryne' = toad (highlighting the single most important distinguishing feature of this genus: the absence of a preopercular spine) (Ref. 86949).

Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 3; Anal soft rays: 3. Diagnosis: Metamorphosed females of Acentrophryne longidens differ from A. dolichonema in having a much shorter distal escal appendage (2.3-2.5% SL vs. 27.6-35.7% SL); a shorter illicium (35.7-54.9% SL vs. 63.6-70.5% SL); a wider head (35.7-37.3% SL vs. 25-28.1% SL); and a greater number of pectoral fin rays (18-19 vs. 16) (Ref. 54827); caudal fin rays 9, ninth ray (ventral most) 18.6-22.6% SL (Ref. 86949).

Estimates based on models

Preferred temperature (Ref. 123201): 7.2 - 11.4, mean 9.6 °C (based on 13 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01995 (0.00906 - 0.04395), b=3.01 (2.83 - 3.19), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.5 ±0.6 se; based on size and trophs of closest relatives

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