Agreed

Comes in a range of colours, including piebald!

Loss of periostracum

This specimen looks pale due to loss of the chitinous periostracum layer caused by weathering. This is not the same as a range of colours of the underlying shell itself.

Thanks Martin - a good response.
I spent time with a binoscope on the ones for my study. In the blotchy ones and those with a much paler complexion, I didn't note a peeling periostracum as a factor.
This though http://www.ispotnature.org/node/311278
might prove how UNobservant I am!
So, off I go tomorow to look at some of my marked ones and start to note seasonal periostracial changes.
I'll post
