Description
The Blue-rayed Limpet is a small, marine gastropod mollusc known for its distinctive shell. It is characterized by a translucent, low-conical shell adorned with striking iridescent blue radiating lines or rows of dots. These limpets are typically found attached to the stipes and fronds of large brown algae (kelp) in the North Atlantic.
