Abyssal Zone

The bathymetric ranges of the same deep-sea (2000 m) species in the Sea of Japan and outside it are compared. Among 85 deep-sea species of the Sea of Japan mega- and macrofauna, 25 species are known outside the sea at the depths greater than 2000 m and 45 species are known outside the sea only from the sublittoral and bathyal (2000 m). Remaining 14 species are endemic to the Sea of Japan. The species of the first group, together with eurybathic Sea of Japan endemics (8 species) are classified as pseudoabyssal. The term pseudoabyssal species is used here for eurybathic (sublittoral-abyssal or bathyal-abyssal) species, the distribution of which is restricted to a relatively small area in the abyssal, in present case, to the abyssal within the Sea of Japan. The share of pseudoabyssal species in the abyssal basin of the Sea of Japan (64%) is larger than in any other abyssal region. It is suggested that the large share of pseudoabyssal species is the result of local submergence of the sublittoral-bathyal fauna into the abyssal zone of the Sea of Japan. The abyssal basin of the Sea of Japan is distinguished as a biogeographic province within the abyssal biotic zone.

We recently found Cribrinopsis japonica Tsutsui & Tsuruwaka, 2014 (Shinkai-hakutou-ginchaku in Japanese name) at the depth between 384 and 800 m in Toyama Bay, Sea of Japan. Since then, C. japonica has been reared under atmospheric pressure in the laboratory for seven years. C. japonica may use a fluorescent protein carried in its tentacles to lure shrimp (Tsutsui et al., 2016*1). However, the ecology of C. japonica in the deep-sea is hardly known. To elucidate the unknown ecology, we coupled one of the first long-term in situ studies of deep-sea organisms with complementary laboratory experiments. Our exploration of deep-sea benthos revealed that C. japonica inhabits the deepest areas of the sea floor at 1,960 m. Moreover, 80% of C. japonica in the deep-sea stayed together with the deep-sea shrimp. In the laboratory environment, when we added the same shrimp species which was observed in situ to the rearing tank with C. japonica, C. japonica stayed closer with the shrimp without attacking using the tentacles. It is rare to observe different animals together at one place or space since there are very few animals in the ocean floor at > 1,000 m depth in the Sea of Japan (Motokawa & Kajihara, 2017*2). In such depopulated environment, it is conceivable that C. japonica and the shrimp may receive benefit mutually or one side by establishing a ‘symbiotic relationship.’ We will elucidate their relationship in more details by studying the possible ‘symbiosis’ in the laboratory.
