				Reef-associated; depth range 0 - 125 m (Ref. 105618).  Tropical; 32°N -   31°S, 30°E -   108°W

				Maturity: Lm ?  range ? - ? cm Max length : 14.0 cm CL male/unsexed; (Ref. 128968)			
			
			
						
			
			
			
			
				
					Adults are found under rocks and  burried in sandy mud (Ref. 128968). The pentagon-shaped carapace and appendages are covered with spines. Pincers are unequal in size, length of which are double the size of the carapace (Ref. 128968). May contain toxins that are undectectable in tests (Ref. 107779), and thus, may not be safe to eat (Ref. 128968). Prefers sandy substrates (Ref. 2899).  Subtidal (Ref. 106854).  Large chela is used to crush snails and molluscan shells of hermit crabs.  Reported to be mildly toxic to toxic.  Toxicity of its flesh may be a result of accumulation of toxins from its diet (Ref. 102986).				
			
			
			
			
			
				Life cycle and mating behavior				
					Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae				
			
			
				
					Members of the order Decapoda are mostly gonochoric.  Mating behavior:  Precopulatory courtship ritual is common (through olfactory and tactile cues); usually indirect sperm transfer.
