Other behaviours and adaptationsOnce a suitable covering is found, the Decorator Crab snips it off with its pincers, coats the end with a special gland secretion that hardens in seawater, and deliberately places it onto its carapace. The crab continues the process until it is sufficiently covered. The algae continue to grow once attached, helping the concealment.
This and other decorator crabs belong to the spider crab family, Majidae. This group includes the largest crab in the world - the Giant Japanese Spider Crab (Macrocheira kaempferi) with a leg span of over 2 m.
