Flat Periwinkle shells! 🐚 🧡💛🐌 😍
They are some of the most colourful inhabitants of our rocky shores. Living amongst brown seaweeds such as bladderwrack, these tiny snails can be found in an astonishing variety of colours, including bright yellow, orange, green, brown and almost black, with many displaying bands or mottled patterns.This colour variation helps them blend into different seaweeds, reducing the risk of being spotted by predators. Slow-moving but perfectly adapted to life between the tides, they spend their days grazing on microscopic algae coating the seaweed.
