I just liked the idea of a whelk called Deborah. (It's not a common name with shellfish).
When I was in the Philippines, we spent a few days on the small island of Boracay, off the larger Panay Island. I booked a chalet near the beach, and one evening heard the sound of a creature clattering across the paved area outside. I took a photograph.
Meet Helen, the Land Hermit Crab. (People actually keep these as pets in some parts of the world).

I think it should be Lady Helen Crustacea.
