Etymology: Eustomias: Greek, eu = good + Greek, stoma = mouth (Ref. 45335); posti: Named for Alfred Post.
Eponymy: Alfred Post (d: 1935) is a German zoologist who worked at Hamburg’s Institut für Seefischerei. He was honoured for his contributions to our knowledge of deep-sea fishes and his continuing services to the ichthyological community. (Ref. 128868), visit book page.

Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 25; Anal soft rays: 38; Vertebrae: 67. Two terminal bulbs separated by a long interspace, 1.3-2.5 times the length of distal bulb. Barbel length 43-50% SL. Four long filaments, arising together from distal end of distal bulb or from a short stem; all with numerous conspicuous bulblets of variable size. Distal bulb 0.9-1.6 times length of proximal-bulb. Axis of stem lightly, often sporadically pigmented; axis between bulbs and in filament lightly or unpigmented. Suggestion of spot at base of distal bulb in one specimen. External chevron-shaped or roundish striated areas unpigmented. Middorsal paired spots between occiput and dorsal-fin origin 8, sometimes 7 (Ref. 11333).

Estimates based on models

Preferred temperature (Ref. 123201): 24.8 - 25.7, mean 25.3 °C (based on 2 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): 4.3 ±0.8 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Assuming tmax>3).

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