| Abstract |
Two aegid isopods were collected from the depth of 800–1200 m, off the coast of Rausu, in the Nemuro Strait of Hokkaido, northern Japan using deep-sea gill net. We have been rearing these isopods in the Aquamarine Fukushima (AMF) for about the past two years. One of the isopods died, and we performed morphological and molecular analyses on it. The morphological characters of the present specimen were in good agreement with the previous descriptions of Rocinela angustata Richardson, 1904. On the other hand, molecular analysis revealed that the present specimen’s cytochrome c oxidase subunit I sequence shared only low similarity with those of R. angustata present in the GenBank. We also provide brief description of the rearing record of these isopods in the AMF here. |
