Decorator Spider Crab

Every decorator crab in this family carries a set of hooked bristles across its carapace built for one job: snagging drifting algae and debris and holding it in place as a living disguise. Watch one long enough and you'll catch it actively grooming and rearranging its own camouflage, plucking off dead material and replacing it — genuine maintenance on a costume it built itself.
