This miniature crab was hiding in a shell I brought home on Canada Day. He's about 1/4 inch across, and spends his time hiding under the edge of the clamshell, where he matches the white of the barnacles on top. Only when he ventures out to grab a bite to eat, does he expose those brown and orange legs; they look borrowed, not really his; they don't match.
I can't tell what species he is yet. He's too small, and too shy. His colours may change as he grows, too.
