Madagascar periwinkle requires water if it is drooping. The breeding habits of periwinkles are quite variable. These tiny blue snails are about the size of your little fingernail and are the most abundant molluscs on the rocky shore, generally found toward the high-tide mark. Clear-cutting of mangrove forests for fish farms Another hypothesis is that a mature snail has a change in the shell surface that makes it suitable for P. ciliata larvae to settle. On a cloudy day, they emerge to feed without risk of the suns drying heat, slowly lapping diatom films from cool stone.
