Neolithodes agassizii is a species of king crab native to the Western Atlantic. They live at depths of 200–1,900 metres (660–6,230 ft),[3] and have been found as far south as Rio de Janeiro,[4] as far north as latitude 36°,[5] and near the Equator.[6] It has been found in the southwestern Caribbean Sea as well as the Gulf of Mexico.[7][8]

Appearance
editN. agassizii has a pyrifrom carapace; the largest adult specimen at the time of description, a female, had a carapace measuring 123 mm (4.8 in) in postrostral length and 117 mm (4.6 in) in width.[1] Whereas its carapace is about 9⁄10 as wide as it is long in adults, this is closer to 8⁄10 in juveniles.[1] The spines around the margins of its carapace are slightly larger than those on its dorsal surface, and between these marginal spines are tubercles.[1] Its rostrum is very short.[1] Its chelipeds feature little spination and are similar in length, but the right is stouter than the left.[1] Its rear walking legs – the longest pair – are nearly three times as long as the carapace width, and all of its dactyli are slightly curved and armed with small, sharp spines.[1] Its underside features a symmetrical abdomen in juveniles, but in adults, there is a noticeable asymmetry in the third, fourth, and fifth segments – its left side is well-developed at the expense of the right side.[1] Its second abdominal segment bears prominent spines.[1]
