One of the recent additions to our little marine aquarium was a hermit crab. He turned up in a chocolate brown periwinkle shell. A couple of days later he had upgraded to a dogwhelk shell.
The other day I spotted him, out and about and very active – which is unusual. I snapped some video in action and it was so fascinating that I just kept rolling.
The camera is a but shaky — couldn't be helped. Focus isn't great — I just wish the camera could get closer.
