Plesionika narval

The Plesionika narval (Fabricius, 1787) group is characterized by the rostrum being very long and armed with numerous closely set teeth along almost the entire length of both borders. The species belonging to this group were placed previously in the genus Parapandalus Borradaile, 1900, because they lacked epipods on the pereiopods but this genus has been synonymised recently with the genus Plesionika Bate, 1888, by CHACE (1985). Members of this group are numbered among the common carideans in deep-water samples and they are known generally as P. narval (Fabricius, 1787) in the Mediterranean and Atlantic.
