Morphology | Morphometrics
Oceania: Northern Australia and central-southern New Guinea, but there are no precise locality records from New Guinea and its occurrence there needs confirmation.
Adults inhabit rivers, creeks and billabongs, usually in quiet or slow-flowing water among vegetation, around log debris or beneath undercut banks. Feed on insects, fishes and crustaceans. Spawn between October and February. The male guards the nest, which is located on a solid surface, frequently on the ceiling of a rock crevice or on a submerged log. Each nest contains up to 70, 000 eggs. The incubation period lasts between 5-7 days (Ref. 44894).

Estimates of some properties based on empirical models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00391 - 0.02557), b=3.01 (2.79 - 3.23), based on LWR estimates for this Subfamily-BS (Ref. 93245
Resilience (Ref. 69278
): High, minimum population doubling time less than 15 months (Fec = 70,000).
Vulnerability (Ref. 59153
): Moderate to high vulnerability (53 of 100) .
