Observation - Bristly Mail-shell. Description: A close encounter with this delightful, far less common here, Chiton. Bigger than any chiton I've so far seen - TWENTY is 9mm.

A close encounter with this delightful, far less common here, Chiton.
Bigger than any chiton I've so far seen - TWENTY is 9mm.
