Etymology: Brosmodorsalis: Greek, brosomai, bibrosko = to eat up, to devour + Latin, dorsus = back, on the back (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Ecologia
marino demersale; distribuzione batimetrica 0 - 17 m (Ref. 9003). Temperate
Southwest Pacific: endemic to New Zealand.
Size / Peso / Age
Maturity: Lm ?  range ? - ? cm
Max length : 6.0 cm TL maschio/sesso non determinato; (Ref. 9003)
Spine dorsali (totale): 0; Raggi dorsali molli (totale): 71-80; Spine anali 0; Raggi anali molli: 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.

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 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).
Trophic level (Ref.
69278): 3.2 ±0.5 se; based on size and trophs of closest relatives
Resilienza (Ref.
120179): Basso, tempo minimo di raddoppiamento della popolazione 4.5 - 14 anni (Assuming Fec < 100).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
