Abstract

RESEARCH NOTE Eggs of Rossia mollicella (Cephalopoda: Sepiolidae) deposited in a deep-sea sponge 1 2 Takashi Okutani and Takenori Sasaki Japan Agency for Marine-Earth Science & Technology, 2-15 Natsushima-cho, Yokosuka, Kanagawa 237-0061, Japan; University Museum, University of Tokyo, 7-3-1 Hongo, Bunkyo-ku, Tokyo 113-0033, Japan developed. However, the observation of the tentacular club During the cruise of the R/V Tansei-Maru of the Ocean Research with a scanning electron microscope revealed that the Institute, University of Tokyo, the second author (TS) collected suckers are developing into approximately eight rows a hexactinellid sponge with eggs of Rossia, from bathyal depth in (Fig. 1G) rather than in a diffusing pattern. This character the Sea of Enshu-Nada in Japan, using a 3 m Oregon-type beam 0 0 0 0 strongly suggests that this embryo belongs to R. mollicella. trawl (34820.09 N, 138800.70 E–34819.53 N, 138801.48 E, The possession of a pair of papillae on both sides of the 563–605.3 m deep at Station EN3-1 in the cruise KT-02-05 rectum, which is one important character of R. bipapillata,is on May 25, 2002).
