Blue shield limpet

Lottia pelta


This was an interesting find - a colony of limpets with a blue shell. There are not any blue limpets that I could find on the internet. Fortunately in the second picture there is a limpet on the left side that revealed some of the story. It is a Shield limpet with faint ridges and revealing a blue color underneath the outer layer. I'm not sure what is causing the blue color.


Spotted on an exposed rock at low tide.

Thank you Sukanya and Mark. It was really interesting the blue limpets only existed on the one boulder. There was a fresh water stream flowing nearby as well.

That really is a nice blue whatever it is. Barnacle friends show no such color.
