Larval stages of Chorismus tuberculatus (Bate, 1888) (Decapoda: Caridea: Hippolytidae) from the southwestern Atlantic Ocean
The present work provides a first description of three planktonic larval stages of Chorismus tuberculatus which were obtained from plankton samples collected in the south-western Atlantic during the expeditions of the RVs 'Walther Herwig' and 'Shinkai Maru' in 1978 and 1979, resp...
