Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5156   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01514 (0.00700 - 0.03275), b=2.97 (2.80 - 3.14), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
營養階層 (Ref. 69278):  3.9   ±0.6 se; based on size and trophs of closest relatives
回復力 (Ref. 120179):  中等的, 族群倍增時間最少 1.4 - 4.4年 (Assuming Fec<1000).
