These little desktop crabs are ready to hold your pens, business cards, eyeglasses, or even a steak knife in their pincers. Designed by Japanese artist Ahnitol, the crabs are available over on Etsy shop CrabCakes Crafts individually or in a set of four. They also sell a lobster with slightly larger claws.
Jonathan Bird’s Blue World shares footage of one of nature’s odd relationships – as a hermit crab helps move a pair of anemones from her old shell to a bigger one. The anemones offer the crab protection, and the crab offers food to the anemones. (Thanks Paul!)
