I’m a huge fan of hermit crabs. It’s not often that a new one comes along. I doubt this is one I will ever see for sale in the hobby but still it’s nice to see new discoveries. Hermit crabs are among the easiest things to keep in a marine tank and are incredibly enjoyable to watch. Of course many of them aren’t reef safe so you have to be quite careful which ones you pick. They can be a very useful member of your clean up crew.
Most hermit crabs use shells built by evicted gastropods (e.g. snails) for protection, but not this new green-eyed species. The “shells” of Paragiopagurus atkinsonaeis are actually permanent colonies of zoanthids who glue together sand into a non-calcified armor, so these “living shells” grow with the hermit crab!
