Short description Morphology | Morphometrics

Fewer sawteeth (normally 19, rarely 20 on a side). First dorsal fin originate in advance of the origin of the pelvic fins and much more deeply concave posterior margins of the dorsal fins. Saltwater species when fresh-caught, either dark gray or golden brown, while freshwater species are mouse gray with reddish along midback posterior to first dorsal fin, reddish posterior to lower part of sides, first dorsal pale yellow with reddish free rear corner; second dorsal, pelvic fins, caudal and lower sides posterior to first dorsal dull brick red. Reddish tint either normal or result of suffusion with blood below the skin (Ref. 6902).

Biology     Glossary (e.g. epibenthic)

Inhabits shallow water in the vicinity of the shore and estuarine, particularly lagoons. Generally thought to rarely descend below 10m but have been found at 122m in Lake Nicaragua (Ref. 55273). Tends to run farther upstream in large rivers. Found in temperatures higher than 20-30°C (Ref. 6902). Ovoviviparous (Ref. 50449). Minor commercial, for the curio trade (Ref. 37548).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5312   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00851 (0.00413 - 0.01752), b=3.00 (2.81 - 3.19), based on LWR estimates for species & Subfamily-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  4.0   ±0.6 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  Low, minimum population doubling time 4.5 - 14 years (Fec assumed to be <100).
Vulnerability (Ref. 59153):  Very high vulnerability (78 of 100) .
Price category (Ref. 80766):   Medium.
