Taxonomic features and identification of Oxycephalidae (Platysceloidea, Physocephalata, Hyperiidea, Amphipoda)

K.K.C. Nair


Oxycephalidae is a group of curious holoplanktonic crustaceans. They are common in the plankton of the offshore waters of the tropical and subtropical regions. Carcinologists have taken to this group only recently inspite of their abundance, probably because of the high variability of morphological features which make specific identification difficult. This contribution endeavours to elucidate and combine available information together with detailed illustrations for easy identification of the species. Taxonomy of the family is discussed with notes on inter- and intra-specific variations. Geographical distribution, ecophenotypic variations and biology of the species involved are mentioned. A detailed bibliographic account on the family is also provided
