Description
Color: Dark brown, whitish.

The “rough” Littorina, which is one meaning of the Latin name scabra (another is “scabby,” which would also fit a brown-spotted shell) is an extremely ubiquitous species throughout the Indo-Pacific wherever there are mangroves or even wood pilings. Its comparatively large size would appear to make it easily visible were it not well camouflaged on mangrove trunks and branches. The relatively long synonymy is a partial indication of its variability. the species produces an almost endless variety of color and sculptural forms from the “typical” dark drown mosaicly banded scabra to the whitish rather smooth albicans described by Metcalfe. The morphological diversity is probably due to the fact that scabra is ovoviviparous and produces closely related, inbred populations within which variations or mutations may develop and are perpetuated. The same phenomenon takes place in the Atlantic subspecies, angulifera whose biology is similar to scabra (Lederking, 1954; Struhsaker,1966).

Fertilization is internal, and pelagic development is the rule, although several species have evolved ovoviviparity.
