An easterly swell will often wash up live trough shells. The large black-backed gulls know to drop them from a height to gain access to the food inside.
The hermit crab was right at the tide line. Every wave turned it over and left it exposed and covered in grit. It used its pincer to wipe the grit off itself just in time for the next wave. And so on. I took a few photos then moved it to a sheltered spot where the rest of the hermit crabs seemed happy. Its home is an ostrich foot shell.
This page highlights one photo from each outing. The subjects will vary - it will be whatever caught my eye or was most special on that day.
