Short description Identification keys | Morphology | Morphometrics

Vertebrae: 102 - 108. Belongs to the group of anguillas which have a short dorsal fin which originates slightly before the anus (Ref. 48622). Most closely resembles Anguilla australis and A. bicolor, from which it can be distinguished with certainty only by the number of vertebrae. Also Ref. 2847.

Inhabits freshwater streams, lakes and swamps, favouring coastal lagoons and the lower reaches of rivers. Spawning adults occur in marine waters. Sub-adults spend most of their lives in fresh or brackish waters (Ref. 44894). Found in large turbid rivers and small creeks (Ref. 2847). Occurs both in running and stagnant waters (Ref. 12790). Feeds mainly on fishes, crustaceans and mollusks.

Estimates based on models

Preferred temperature (Ref. 123201): 3.6 - 10.2, mean 4.8 °C (based on 263 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00050 (0.00030 - 0.00083), b=3.15 (3.01 - 3.29), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.5 ±0.80 se; based on food items.

Resilience (Ref. 120179): Very Low, minimum population doubling time more than 14 years (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): High to very high vulnerability (66 of 100).

Price category (Ref. 80766): Unknown.
