Teleostei (teleosts) > Saccopharyngiformes (Swallowers and gulpers) > Monognathidae (Onejaws)
Etymology: Monognathus: Greek, monos = one + Greek, gnathos = jaw (Ref. 45335); herringi: Named for Peter J. Herring who was of great help to the authors by collecting and preserving Monognathus material on board the "Discovery".
Eponymy: Dr Peter John Herring is an oceanographer and deep-sea biologist, whose bachelor’s degree and doctorate were both awarded by Cambridge. [...] (Ref. 128868), visit book page.

Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 78; Anal soft rays: 58. M. herringi differs from the other species of the genus by the following combination of characters: head long with elongate, pointed snout, skull length 6.4% TL, rostral fang strongly hooked with distal part in a nearly right angle to dorsal profile of skull, anal fin origin below myomere number 28, and no lateral, subdermal spots of pigmentation.

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00102 (0.00046 - 0.00225), b=3.06 (2.88 - 3.24), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

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

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