Length at first maturity / Size / Weight / Age
Maturity: Lm 7.2  range ? - 6.19 cm Max length : 15.0 cm CL male/unsexed; (Ref. 343); 12 cm CL (female); max. published weight: 900.00 g (Ref. 343); max. published weight: 900.00 g
Carapace very elongate, much longer than broad; anterior part much broader than narrow, posterior waist-like. Abdomen clearly visible from dorsal view. Chelae greatly outsized in males; chelae and legs laterally flattened, spade-like. Color: orange to red overall.
Minimum depth from Ref. 114541. Occupies the sublittoral zone (Ref. 77016). Occurs at depths greater than 100 m in open sandy areas (Ref. 343) in which they bury (Ref. 106934). Feeds on a variety of worms and soft shelled mollusks (Ref. 343). Members of the order Decapoda are mostly gonochoric. Mating behavior: Precopulatory courtship ritual is common (through olfactory and tactile cues); usually indirect sperm transfer (Ref. 833).
