Littoraria scabra , common name : the mangrove periwinkle , is a species of sea snail , a marine gastropod mollusk in the family Littorinidae , the winkles or periwinkles.[ 1]

Description
The size of an adult shell of Littoraria scabra varies between 15 mm and 40 mm.[ 2] These shells are ovate-conical, without an umbilicus. The outer surface shows a spiral sculpture without nodules, with a pattern of irregular dark stripes.[ 4] As in other bark-living snail species the shell color is brown. The mouth is rounded and the radula quite long, in order to adapt to the surface or the bark.[ 5]
Biology
These snails are grazers on the roots, trunks, branches, and leaves of their host plants where they feed on zooplankton, bacteria, algae and mangrove tissues. These generalist herbivores daily vertically migrate along mangrove trees to avoid tidal submersion.[ 6]
