Dorsale stekels (totaal) : 0; Dorsale zachte stralen (totaal) : 71 - 80; Anale stekels: 0; Anale zachte stralen: 35 - 41. Head and body peach-like orange pink, slightly paler ventrally. Adult males with a distinctive whitish streak along the belly. Distinguished from other brotulas by the dorsal fin which begins forward of the gill cover and has the first rays free of membrane.

Uncommon to locally abundant cryptic species found in areas with dense algal growth (Ref. 34024). Sometimes in rock pools (Ref. 9003).

Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00457 (0.00179 - 0.01169), b=3.10 (2.87 - 3.33), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

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

Weerstandsvermogen (Ref. 120179): laag, minimale populatieverdubbelingstijd 4,5-14 jaar (Assuming Fec < 100).

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