gastropod shell The gastropod shell is part of the body of a Gastropoda, gastropod or snail, a kind of mollusc. The shell is an exoskeleton, which protects from predators, mechanical damage, and dehydration, but also serves for muscle attachment and calcium s ...

. The shell is yellowish to brownish, smooth or with fine striation. It is shiny. There are 7-8 slightly convex whorls. The apertural margin is white and usually with a white layer at the parietal side. The parietalis is very strong and horizontal and often a small second parietalis is present. The columellaris is strong and the umbilicus is usually covered. The form '' denticulata'' has 3-6 short and thin folds (like drops) near the palatal margin at the inner lip. Myosotella myosotis 01
