Stenomelania denisoniensis is a very variable species of freshwater snail, an aquatic gastropod mollusk in the family Thiaridae.[2] Stenomelania denisoniensis has a long, slender shell and small aperture. This species has a characteristic angled shoulder just below the suture. This shoulder may be strong in some individuals and weak in others even if they are part of the same population.[3]

Biology and ecology

[edit]

"On and in sediment, rocks and on water weeds in freshwater rivers, streams, lakes and dams. A detritus and algal feeder. Stenomelania denisoniensis broods larvae in a brood pouch in the head which may contain a dozen shelled juveniles and many unshelled juveniles in different embryonic stages."[3]

Distribution

[edit]

Distribution of Stenomelania denisoniensis is endemic to Australia and includes New South Wales and Queensland, the Northern Territory and Western Australia[1] Is found most commonly found in tropical and subtropical Australia (the northern half of the continent).
