GASTROPODA | LITTORINIDAE |
Shells very small to small, solid, with a globose, turbiniform or trochiform outline, with a surface smooth, spirally striated, or nodulose; aperture entire, suborbicular, angular posteriorly, round anteriorly. As their shells lack distinctive characteristics, often these animals cannot be assigned to this family without collateral informations (anatomy, ecology). |
