Golden Apple Snail/Channeled Apple Snail

Description:

Snail shells found at the edge of a wetland area. The locals eat these snails

Habitat:

Apple snails inhabit various ecosystems: ponds, swamps and rivers. Although they occasionally leave the water, they spend most of their time under water. - Wiki

Notes:

Apple snails are exceptionally well adapted to tropical regions characterized by periods of drought alternating with periods of high rainfall. This adaptation is reflected in their life style; they are moderately amphibious. They have an operculum which enables the snail to seal the shell entrance to prevent drying out while they are buried in the mud during dry periods. - Wiki
