Palaemonetes


Palaemonetes, its common names include grass shrimp, ghost shrimp, feeder shrimp, is a genus of caridean shrimp comprising a geographically diverse group of fresh water, brackish and marine crustaceans. Conventionally, Palaemonetes included the following species:
Molecular data suggest however that Palaemonetes is not phylogenetically distinct from the genus Palaemon. Phylogenetically species of Palaemonetes, as well as those in the genera Exopalaemon and Couteriella, are nested within Palaemon. Phylogenetic affinities in these groups correspond better with geographical origin than conventional genus assignments. Palaemonetes has therefore been synonymised with Palaemon.
