Neripteron vespertinum is a species of freshwater snail,[3] an aquatic gastropod mollusc in the family Neritidae.
Description
Its shell is flattened, generally thin, covered in a thick epidermis, and has a smooth interior and exterior.[4] The shell has an apparent olive green color that slickly grades into a dark black or a light brown color.[5] The width of the shell can go up to 1 inch, with wing resembling projections that start from the apex.[5]
Distribution and habitat
This species is endemic to Hawai'i[4] and is traditionally found on all the Hawaiian Islands.[6] This mollusk is almost always found in freshwater,[4] specifically the slightly briny bottommost untouched small streams near big rocks.[7] They are also found in estuaries, on firm surfaces such as rocks, boulders, and bridge supports.[8]
Conservation status
The conservation status for the N. vespertinum is currently critically imperiled. Possible or ongoing threats to this mollusk include stream channelization and burial, pollution, water diversions; which have strained the distribution and abundance of these mollusks. Even more so, runoff or extensive flooding-resulting in high sedimentation turbidity, nutrients, trash and other pollutants emptying into streams, rivers, estuaries, and oceans also pose a crucial threat.[6]
