The biology of Natatolana borealis, a deep-sea (−500 m) scavenging isopod that lives on the continental slope of Mediterranean canyons, was studied in the field and in the laboratory. Animals were collected at two stations using a baited trap. Whatever

Postmarsupial development and growth of Natatolanaborealis were studied from Skogsvåg and Raknesvåg on the western coast of Norway. Growth was determined from size and instar stage distributions. Growth was also examined in laboratory kept isopods that

The scavenging deepwater isopod Natatolana borealis (LILLJEBORG) was caught off Bergen on the West coast of Norway in baited traps. N. borealis attained sexual maturity from 6-7 instar. The oostegites were formed in a biphasic parturial-ecdysis. Four
