Teleostei (teleosts) > Anguilliformes (Eels and morays) > Synaphobranchidae (Cutthroat eels) > Synaphobranchinae
Etymology: Synaphobranchus: Greek, syn, symphysis = grown together + Greek, aphoo, aphiemi = to throw + Greek, brangchia = gill (Ref. 45335).
Eponymy: Johann Jakob von Kaup (1803–1873) was a German zoologist and palaeontologist who became the Director of the Grand Duke’s natural history ‘cabinet’ in Darmstadt. [...] (Ref. 128868), visit book page.

Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 270. Dark purplish grey in color (Ref. 3973). Anal rays about 270 (Ref. 3973).

Biology     Glossary (e.g. epibenthic)

Found on the continental slope near the upper limit of abyssal zone (Ref. 6726). Epibenthic (Ref. 58426). Probably most common in 800 to 2,000 m (Ref. 5235). Do not tolerate higher water temperatures (Ref. 5951). Feeds mainly on Decapoda, Natantia, amphipods, but also fishes and cephalopods (Ref. 6726). Caught by bottom longline and baited fish trap (Ref. 85806).

Estimates based on models

Preferred temperature (Ref. 123201): 0.4 - 9.1, mean 3.4 °C (based on 3305 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5156   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00059 (0.00030 - 0.00117), b=3.14 (2.96 - 3.32), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  4.1   ±0.4 se; based on diet studies.
