Clithon spinosum is a species of brackish water and freshwater snail with an operculum, a nerite. It is an aquatic gastropod mollusk in the family Neritidae, the nerites.

Distribution

Distribution of Clithon spinosum include Indo-Pacific and it ranges from New Guinea [3] and south-eastern Asia and eastern Asia to Marquesas. [4] It also occurs in Japan, [5] New Georgia, [6] Fiji [3] and Tahiti [3] and in French Polynesia including the following Society Islands: Tahiti, Mo'orea, Raiatea, Huahine. [4]

Description

There are always spines on its shell. [3] Spines are long and thin and they are directed rearward. [7] The width of the shell is 15–20 mm. [8]

Ecology

Clithon spinosum is a dioecious (it has two separate sexes) and amphidromous snail. [4] Adults live in freshwater and larvae are marine. [4] Larvae are long-lived planktotrophs. [4] Adults prefer boulders and cobbles over granules as a substrate. [7] [5] They were found mainly on bottom of rocks in aquaria and in situ. [7] They are reported from altitude 0–10 m a.s.l.. [7] They can reach densities up to 57.0 ± 17.3 snails per square meter of a stream. [7] Adults can survive 8 hours in seawater (longer exposure was not tested). [7]

It is not used as food source by humans. [4]

Freshwater snail gastropod mollusks which live in fresh water

Freshwater snails are gastropod mollusks which live in fresh water. There are many different families. They are found throughout the world in various habitats, ranging from ephemeral pools to the largest lakes, and from small seeps and springs to major rivers. The great majority of freshwater gastropods have a shell, with very few exceptions. Some groups of snails that live in freshwater respire using gills, whereas other groups need to reach the surface to breathe air. In addition, some are amphibious and have both gills and a lung. Most feed on algae, but many are detritivors and some are filter feeders.
