Habitat specialization by Thia scutellata (Decapoda: Brachyura) off Wales

There are sporadic records of Thia scutellata from Carmarthen Bay, Cardigan Bay and off the north coast of Wales. Relative scarcity of this small burrowing crab is probably due to habitat specialization. It lives in loose very well sorted medium sand, as typically found in parts of sand waves.
