Maturity: Lm ?  range ? - ? cm

Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 11 - 13; Dorsal soft rays (total): 20 - 23; Anal spines: 2; Anal soft rays: 22 - 26. Diagnosis: A good diagnostic characteristic is a short diagonal line found just behind the eye (Ref. 44091). Head without cirri; lower end of gill opening usually opposite 4th or 5th pectoral fin ray; sensory pores in infraorbital an interorbital canals mostly 8 and 3 respectively; lateral line tubes 1 to 4 (Ref. 559).

Biology     Glossary (e.g. epibenthic)

Adults are found in mangrove swamps and river estuaries, but more often in freshwater lakes (Ref. 4404, 58302). Benthic (Ref. 58302). The size and shape of the mouth, the presence of large canine teeth suggest that this fish is probably a predator on small aquatic animals (Ref. 44091). Oviparous; eggs are demersal and adhesive (Ref. 205), and are attached to the substrate via a filamentous, adhesive pad or pedestal (Ref. 94114). Larvae are planktonic, often found in shallow, coastal waters (Ref. 94114).

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=0.00562 (0.00258 - 0.01228), b=3.06 (2.87 - 3.25), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.5   ±0.37 se; based on food items.
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
