Abundant in the Solitary Islands Marine Park. Distributed throughout the south-western Pacific Ocean. In Australia recorded from Darwin in the Northern Territory east through Queensland and south to at least Sydney in New South Wales.

Frequents unshaded sandy mud in bays, estuaries and creeks. 

Additional Notes:

Males have a conspicuous orange coloured dominant claw (or chelae), that is used to repel other males and to attract females. The eyestalks are long and thin, and the carapace is brown-black in colour with blue green blotches. The claws on the female are small and blue green in colour. Grows to around 30mm across the carapace.
