Diet edit
The diet of this crab is largely unknown; however, it is considered a large omnivore that has been noted to feed on algae and carrion.[6] Unlike crabs such as the blue crab, the West Indian spider crab is not commercially harvested for its meat.[4]
Description edit

M. spinosissimus has a reddish-brown carapace and walking legs. The claws are smooth, purplish gray, with a single row of nodules along the outer edge, and blunt claw tips. The legs are covered with numerous short spines and nodules. It is the largest native crab species of the Atlantic. It can reach up to 3 kg of weight and a carapace length of 18 cm.[3]
Distribution edit
M. spinosissimus is found from North Carolina to Venezuela. It inhabits caves and reef underhangs from the shallow intertidal to depths of up to 200 m.[3]
It was made the type species of a separate genus Maguimithrax by Klompmaker et al. (2015).[7]
Human intervention edit
Mote Marine Laboratory in Florida is spawning the crabs in hopes they will eat algae and benefit coral reefs.[8][9]
