Majidae is a family of crabs, comprising around 200 marine species inside 52 genera, with a carapace that is longer than it is broad, and which forms a point at the front. The legs can be very long in some species, leading to the name "spider crab". The exoskeleton is covered with bristles to which the crab attaches algae and other items to act as camouflage. ==Genera== The roughly 200 extant and over 50 extinct species are divided among 52 genera in 5 subfamilies: ''Eurynolambrinae'' Števčić, 1994 *''Eurynolambrus'' H.
