Biology     Glossary (e.g. epibenthic)

Adults inhabit bays and estuaries (Ref. 37955). Also found in high altitudes of at least 250 m elevation and a distance of some 20 km from the coast. They also occur in coastal waters, but is more abundant in estuaries of any size. Enter freshwaters mostly in large rivers and feeds on fish and crustaceans (Ref. 36880).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5005   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00776 (0.00454 - 0.01328), b=3.03 (2.88 - 3.18), in cm Total Length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  4.0   ±0.65 se; Based on food items.
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low to moderate vulnerability (29 of 100) .
Price category (Ref. 80766):   Very high.
