This crab is the size of a riding horse, with a square-shaped reddishbrown carapace covered with dark-red and yellow markings. Flames lick its body, erupting at irregular intervals from its underbelly. Its eyes are perched on the end of two large eyestalks that protrude from the center of the carapace.
