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] Paracrangon species lack their second pereopods, and, as they are often used for grooming, their absence may explain why they are frequently found covered with detritus, hydroids, and bryozoans.

[2] Paracrangon species are slightly compressed laterally, have free eyes, and an elongated rostrum that is relatively slender and sub-erect.

[7] A 2011 study found that P. echinata is a lie-in-wait predator, feeding on smaller organisms, primarily amphipods (which constitute over 40% of the diet), polychaetes, and other carideans.
