Does A Fiddler Crab Fiddle? No! But fiddler crabs sure do some amazing things! Starting with silly questions like the title, and moving on through increasingly-unlikely questions such as "do fiddler crabs ride a skateboard?," and "do fiddler crabs eat pizza?," children discover what fiddler crabs do. They don't need a skateboard they can move sideways so shore birds can't catch them. They may not enjoy pizza, but they gobble up saltmarsh muck.
