Biology
This species of Leptomithrax is much like L. gaimardii but only one-third as big. The carapace, rostral spines and eye orbit are similar but its legs don't extend forward much beyond the rostrum as they do in L. gaimardii. Although it is just as common as the great spider crab over a wide depth range, its denser camouflage ensures it is less commonly seen.
