Blue Rayed Limpet
These small limpets feed on kelp, and are often seen chomping their way across a kelp leaf. Each shell has beautiful iridescent blue lines across it which glitter in the sunshine.

This small limpet has been rasping away at the kelp leaf, leaving a clear trail of damage (above it is a grey topshell)
