Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00776 (0.00343 - 0.01757), b=2.97 (2.79 - 3.15), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
مستوى غذائي (Ref. 69278):  3.3   ±0.5 se; based on size and trophs of closest relatives
المرونه (Ref. 120179):  عالي, الحد الزمني الأدني لتضاعف عدد أفراد المجتمع أقل من 15 شهر (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
