| metazoan parasites and food composition of juvenile etmopterus spinax (l., 1758) (dalatiidae, squaliformes) from the norwegian deep. | a total of 37 juvenile etmopterus spinax from the norwegian deep were examined for stomach contents and metazoan ecto- and endoparasites. these squaliform elasmobranchs were caught by benthopelagic net in may 2001 at a depth of 194-214 m. the euphausiid meganyctiphanes norvegica and the teleost maurolicus muelleri were the principal prey organisms. with increasing total length of e. spinax, the frequency of meganyctiphanes norvegica prey decreased and that of m. muelleri increased. seven differe ... | 2003 | 12632160 |
| two new species of aporhynchus (cestoda: trypanorhyncha) from deep water lanternsharks (squaliformes: etmopteridae) in the azores, portugal. | new collections of cestodes from the spiral intestines of the lanternsharks etmopterus spinax and etmopterus pusillus off the island of faial, in the azores, atlantic ocean, have yielded 2 new species of trypanorhynchs belonging to aporhynchus. both species share the distinctive lack of all elements of the rhyncheal system that are characteristic of this genus. the identity of aporhynchus norvegicus is clarified to allow it to be distinguished from a. menezesi n. sp., which also parasitizes e. s ... | 2010 | 21158633 |
