Hermit crabs are always fun to watch. These two were squabbling for several minutes. One was out of its shell and trying to get back in. Eventually the aggressor got in to the empty shell and the defender went into the now vacant aggressor's shell and they both scuttled away. The reason for the swap wasn't apparent - both shells were neritas about the same size.
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.
