Etymology: Facciolella: Latin, diminutive of falx, falcis = sickle (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; bathydemersal; depth range 700 - 2000 m (Ref. 9942). Deep-water

Western Indian Ocean: Red Sea. Larvae were reported from the northwestern Indian Ocean.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
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
= 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00089 (0.00035 - 0.00227), b=2.98 (2.77 - 3.19), 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).
