Paracrangon is a genus of deep-sea shrimp in the family Crangonidae, found on the Pacific coasts of North America, Asia, and Australia.[1] Morphologically, they are notable for several autapomorphies, most significantly their unique lack of second pereopods, but also for their partially flexible abdomen, which allows them to assume their defensive cataleptic posture.[2][3][4] Species also have long spines covering their carapace.[5][6] They are distinctive among the Crangonid shrimp, and are almost certainly monophyletic.[2] All species except Paracrangon echinata, the type species, are quite rare.[2]
