Etymology: Facciolella: Latin, diminutive of falx, falcis = sickle (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range

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. 115969
): 21.7 - 21.8, mean 21.7 °C (based on 10 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00060 (0.00023 - 0.00155), b=3.08 (2.86 - 3.30), 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.).
Vulnerability (Ref. 59153
): Moderate to high vulnerability (48 of 100) .
