We may dress in costumes once a year for Halloween, but "designer crabs" use disguises year-round to fool predators and avoid attacks. Pictured is a spider crab, Libinia dubia, from North Carolina, decorated with its favorite seaweed, Dictyota. This seaweed is toxic to predators, so the crab avoids getting eaten by "dressing up" to look like something that predators know is bad for them. (John J.
