Description
Its carapace is ovate and anteriorly broadened, with two short rostral spines projecting forward. The surface of the carapace, chelipeds and walking legs are covered by numerous tubercles. The legs are elongated; its legspan reaches up to 80 cm (31 in).[3] All pereiopods are cylindrical and sparsely setose; the merus of each walking leg bears a row of small spines along the extensor margin.[4] It reaches up to 122 mm (4.8 in) in carapace length; it is the largest spider crab along Macrocheira kaempferi.[5]
