Periwinkle Snails
Periwinkle Snails
Littorinidae
Periwinkle snails are small, colorful snails that live on rocky shores. They have spiral shells that can be blue, gray, or brown, and they love to munch on algae!
生息地: Coastal areas
外見
The Periwinkle Snails has a sturdy, conical or turban-shaped shell that typically ranges from grey, brown, or black to olive green, sometimes featuring subtle banding. Its small size and smooth, often dull, exterior help it blend into rocky shorelines. This distinctively robust shell visually sets it apart from more delicate land snails.
