Classification / Names Common names | Synonyms | Catalog of Fishes(genus, species) | ITIS | CoL | WoRMS | Cloffa

Teleostei (teleosts) > Anguilliformes (Eels and morays) > Nettastomatidae (Duckbill eels)
Etymology: Facciolella: Latin, diminutive of falx, falcis = sickle (Ref. 45335).
Eponymy: Dr Luigi Facciolà (1851–1943) was an Italian physician and ichthyologist who was the first to recognise and describe the Witch-Eel genus (1911) but in doing so used a preoccupied name (Nettastomella). [...] (Ref. 128868), visit book page.

Body shape (shape guide): eel-like.

Biology     Glossary (e.g. epibenthic)

Floating or actively swimming larvae seem to live in the upper pelagic region. In the Red Sea, metamorphosing or post metamorphosed stages seem to descend vertically down to the deep-sea bottom.

Estimates based on models

Preferred temperature (Ref. 123201): 21.7 - 21.8, mean 21.7 °C (based on 10 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5156   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00089 (0.00036 - 0.00222), b=2.98 (2.76 - 3.20), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.4   ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Moderate to high vulnerability (47 of 100). 🛈
