Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.7510 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00437 (0.00171 - 0.01116), b=3.08 (2.86 - 3.30), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Τροφικό Επίπεδο (Ref. 69278): 3.2 ±0.4 se; based on size and trophs of closest relatives

Ελαστικότητα (Ref. 120179): Υψηλό, ελάχιστος χρόνος για διπλασιασμό πληθυσμού < 15 μήνες (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (26 of 100).
