This is a species of large, unnamed crustacean-like creature which lives in the Martian shores.
This animal is described as a crab-like creature, with a stout body - its width greater than its length -, and almost the size of a man. Its legs are disproportionally short, rendering it unable to move at great speed, but this is compensated by a pair of extraordinarily long appendices, armed with powerful claws at the end. Robert Darvel (a French engineer who explored Mars in the nineteenth century) speculated that this creature was built for defense and probably spent most of its time in furrows amidst the rocks.
