Palaemon (shrimp)
Palaemon is a genus of caridean shrimp of the family Palaemonidae. The conventional circumscription of the genus Palaemon is probably paraphyletic. Molecular data suggest that Palaemonetes, as well as the genera Exopalaemon and Couteriella, are nested within Palaemon. Phylogenetic affinities in these groups correspond better with geographical origin than conventional genus assignments.
