Remove ads
Neolithodes is a genus of king crabs in the subfamily Lithodinae.[1] They are found in all major oceans, both in high and low latitudes. Although there are records from water as shallow as 70 m (230 ft) in cold regions, most records are much deeper, typically 700–2,000 m (2,300–6,600 ft), with the deepest confirmed at 5,238 m (17,185 ft).[2][3][4][5][6] They are fairly large to large crabs that typically are reddish in color and spiny, although the size of these spines varies depending on species (from long in species like N. grimaldii to very short in species like N. flindersi, and tending to be more pronounced in small than in large individuals).[4][7]

Interactions with other species
Various sessile organisms such as barnacles are sometimes attached to their carapace and legs,[3][8] and small commensal amphipods may live in their carapace.[9] They are occasionally the victims of parasitic snailfish of the genus Careproctus, which lay their egg mass in the gill chamber of the crab, forming a mobile "home" until they hatch.[4] Conversely, some juvenile Neolithodes have a commensal relationship with Scotoplanes sea cucumbers. To protect itself from large predators, the young crab hides under the sea cucumber.[10]
