Description
Neolithodes agassizii has a pyriform carapace; the largest adult specimen when it was described, a female, had a carapace measuring in postrostral length and in width. Whereas its carapace is about as wide as it is long in adults, this is closer to in juveniles. The spines around the margins of its carapace are slightly larger than those on its dorsal surface, and between these marginal spines are tubercles. Its rostrum is very short. Its chelipeds feature little spination and are similar in length, but the right is stouter than the left. 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. Its underside features a symmetrical abdomen in juveniles, but in adults, there is a noticeable asymmetry in the third, fourth, and fifth segments: the left side is well-developed at the expense of the right side. Its second abdominal segment bears prominent spines.
