Description

Habitat

Typically found in a lake at a mean distance from sea level of -46 meters (-150 feet).[1]

Ecology: This estuarine species is common in the more sheltered parts of mangroves and nipa-palm swamps , and the muddy areas in monsoon drains . It can be found either crawling on the mud or remaining attached to grass in all muddy localities. Its vertical distribution is restricted to 10 m downward from the high water mark . Its shell is usually bright red but occasionally black. It probably feeds mainly on algae (Brown 1971, Brandt 1974, Subba Rao et al. 1992, Tan and Ng 1992).

Abbott (1958) collected this species from wet logs on the muddy banks of the estuarine exit of Bantayan River , north coast of Samar Island, Philippines. He stated that the area is alternately covered by saltwater at high tide and freshwater during low tide . Choy and Booth (1994) documented that this species disappears completely during periods of flooding, but it quickly recovers its pre-flood population levels. [2].
