A. estuarius is endemic to Myanmar where it is found in the large tidal rivers in the lower Ayeyarwady River.[1] This species feeds on comparatively large invertebrates.[1]
A. estuarius has no thoracic adhesive apparatus, a granulate anterior margin of the pectoral fin spine, a smooth to granulate anterior margin of the dorsal fin spine, a slender body shape, moderate gill openings, and a papillate upper lip. The eyes are very small, and the nostrils are much larger than the eyes.[2] This species of fish reaches a length of 4.59 centimetres (1.81 in) SL.[1]
