Estimates based on models

Preferred temperature (Ref. 115969): 27 - 27.8, mean 27.5 (based on 149 cells).

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00457 (0.00212 - 0.00984), b=3.10 (2.93 - 3.27), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic Level (Ref. 69278): 4.5 ±0.80 se; Based on food items.

Generation time: 10.0 ( na - na) years. Estimated as median LN(3)/K based on 2 growth studies.

Resilience (Ref. 120179): Very Low, minimum population doubling time more than 14 years (K=0.11-0.12; tm=5-7; tmax=12; Fec=4).

Vulnerability (Ref. 59153): High to very high vulnerability (74 of 100) .

Price category (Ref. 80766): Medium.
