soft rays: 9 - 10. Resembles A. urotaenia, but differs in having large eye, and a gently-rounded snout. Eye diameter over 30% and interorbital width over 20% of head length. Cheek scales in 2 rows. Attains 8 cm TL.
Inhabits clear, flowing creeks, usually within 20 kilometers of the sea (Ref. 44894). Commonly found in brackish waters and river mouths. Occurs near mangroves, stagnant and running freshwater (Ref. 7300) and coastal areas (Ref. 45255). This species has a marine larval stage, judging from its broad distribution. One of the best viewing areas is at the Freshwater creek picnic ground in Cairns, where individuals frequently aggregate along the vegetated stream margin (Ref. 44894).

Estimates of some properties based on models
Phylogenetic diversity index (Ref.
82805): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01349 (0.00549 - 0.03312), b=3.01 (2.80 - 3.22), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic Level (Ref.
69278): 3.5 ±0.41 se; Based on food items.
Resilience (Ref.
69278): High, minimum population doubling time less than 15 months (Assuming Fec > 10,000).
Vulnerability (Ref.
59153): Low vulnerability (12 of 100) .
