New studies on malacostracan relationships have drawn attention to issues concerning monophyly of the order Mysidacea, manifested in recent crustacean classifications that treat the taxon as two separate orders, Lophogastrida and Mysida. We present molecular phylogenies of these orders based on complete sequences of nuclear small-subunit ribosomal DNA (18S rRNA), and morphological evidence is u...
متن کاملEye function of Mysidacea (Crustacea) in the northern Baltic Sea.
Eye spectral sensitivity, [S(lambda)], was measured in seven northern Baltic mysid species using an electroretinogram technique. Their S(lambda) curves were compared with the spectral distribution of underwater light at their normal habitats. In the littoral species Neomysis integer, Praunus flexuosus and Praunus inermis, the S(lambda) maxima, [S(lambda)(max)], were in the wavelength-bands of 5...

متن کاملFirst record of Tanaidacea (Crustacea) from a deep-sea coral reef in the Gulf of Guinea.
Four undescribed species of Tanaidacea were discovered during a baseline monitoring program conducted off the coast of Ghana. The specimens came from a deep-water reef largely composed of the ahermatypic coral, Lophelia pertusa. The tanaidacean material was collected during November 2012 onboard the RV Dr Fridtjof Nansen using a van Veen grab in depths of between 375 and 386 m. Three of the new...
متن کاملthe first record of argulus foliacesus (crustacea: branchiura) infestation on lionhead goldfish (carassius auratus) in iran
argulus foliaceus (crustacea: branchiura), or the fish louse, is an ectoparasite of the skin or gill of the fresh water fish species. clinical signs in infected fish include scratching on aquarium walls, erratic swimming, and poor growth. it causes pathological changes due to direct tissue damage and secondary infections. in the present study, lionhead goldfish (carassius auratus ), taken from...
