Hemigrapsus sexdentatus is distinctive because of its dark purple colour and it is commonly known as the ‘purple rock crab’. Immature crabs have quite variable coloration with various degrees of pale mottling of the purple ground colour. Its congener, Hemigrapsus crenulatus (H. Milne Edwards, 1837) , has a dark green colour and is much more setose, especially on the pereopods.
