Mangrove periwinkle
Littoraria spp.
Family Littorinidae


Relatives of the common periwinkle (Littorina) of temperate shores, there are at least 10 mangrove species known from Singapore.

Three common species are named for their respective traits: L. carinifera has a carina or prominent rib along its side; L. conica is distinctively conical in shape and L. melanostoma has a black mouth (not shown in photograph).

Most of them live on the leaves and trunks of mangrove trees, probably grazing on leaf hair and epilithic algae, although some species are common on the walls of monsoon drains.

All are well adapted to terrestrial life, spending most of their time out of water even during high tides. However, their young are released into the sea either in egg capsules or as swimming veliger larvae.
