Teleostei (teleosts) > Stomiiformes (Lightfishes and dragonfishes) > Gonostomatidae (Bristlemouths)
Etymology: Triplophos: Greek, triplos = three + Greek, phos = light.
Eponymy: Captain Thomas Henry Heming RN (d: 1856) was (1898–1907) Commander, Royal Indian Marine Survey Steamer ‘Investigator’ from which the holotype was collected. He carried out soundings in the Humber estuary (1909). (Ref. 128868), visit book page.

Estimates based on models

Preferred temperature (Ref. 123201): 5 - 13.6, mean 7.5 °C (based on 245 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00138 (0.00053 - 0.00359), b=3.07 (2.85 - 3.29), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.3 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (34 of 100).
