Introduction Here, we attempt to replicate their experiments with two other species of decapod crustaceans that bracket P. elegans phylogenetically: white shrimp (Litopenaeus setiferus) and Louisiana red swamp crayfish (Procambarus clarkii). Litopenaeus setiferus have a similar ecology to prawns. Procambarus clarkii is widely used in the study of neurobiology, and would be an excellent candidate for further neurophysiological studies.
Discussion We found no behavioral evidence of nociception in either L. setiferus or P. clarkii. This outcome contrasts sharply with results that indicated P. elegans had nociception (Barr et al. 2007).
