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 of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00066 (0.00025 - 0.00174), b=3.08 (2.86 - 3.30), 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. 69278
): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Moderate to high vulnerability (48 of 100) .
