African Periwinkles – Nutritional Values, Types & Benefits
African Periwinkles – Periwinkles are related to limpets, whelks, and other marine snails, is the most common snail in Rhode Island. A single spiral shell that grows with their bodies protects these small snails.
Periwinkles are found in many parts of the world. However, they are considered a delicacy in most African and Asian cuisines.
The body includes a fleshy foot, a short tail, and two antennae on the head. The cream-colored foot of the common periwinkle is divided into a right and a left half, which the snail moves alternately as the muscle ripples forward.
Their stalked tentacles are sensory organs that are used to see and taste.
TYPES OF PERIWINKLES:
There are three types of periwinkles. The Includes:
1. COMMON PERIWINKLES
The common periwinkle can be identified by its striped tentacles and a spire (the pointy end of the shell) that isn’t as sharp as that of the rough periwinkle, but not as smooth as that of the smooth periwinkle.
2. SMOOTH PERIWINKLES
Smooth periwinkles are very smooth, they have a flattened spire and they can be a variety of colors – solid yellow to striped to brown, colors that all camouflage them nicely in the rockweeds they call home.

WHAT DOES PERIWINKLES EAT?
Periwinkles are herbivores, using their file-like tongue, the radula, to feed on diatoms and algae attached to intertidal rocks.
The common periwinkle breaks down its food by mixing it with mucous on the radula before bringing the food into its mouth.
Sea stars, whelks, and some fish eat common periwinkles. The shells of dead common periwinkles are often inhabited by hermit crabs.
