> Stomiiformes (Lightfishes and dragonfishes) > Stomiidae (Barbeled dragonfishes) > Melanostomiinae
Etymology: Melanostomias: Greek, melan, -anos = black + Greek, stoma = mouth (Ref. 45335).
Eponymy: Both these species are named after the research vessel ‘Valdivia’ and the Valdivia expedition (1898–1899), Germany’s first expedition to explore deep seas. The holotypes were collected during the expedition. (Ref. 128868), visit book page.

Estimates based on models

Preferred temperature (Ref. 123201): 6.1 - 15.8, mean 9.9 °C (based on 965 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00302 (0.00116 - 0.00786), b=3.12 (2.89 - 3.35), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.2 ±0.73 se; based on food items.

लौटाव (Ref. 120179): माध्यम, न्यूनतम जनसंख्या दुगनी होने का समय 1.4 - 4.4 वर्ष। (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (14 of 100).
