During capture, the animals were exposed to 10,000- 20,000 lux bright sunlight for about 20 min, but imme- diately after they had been hauled on board the moth- ership Natsushima, the compound eyes of three individ- uals were fixed for 12 h at 4°C in 2% glutaraldehyde and 2%

(a) Dorsal view of specimen with carapace width of 11 cm and legs 30 cm long, (b) Close- up of head region with pair of eyestalks and black shiny eyes, each mea- suring about 4 mm in length in this specimen. During capture, the animals were exposed to 10,000- 20,000 lux bright sunlight for about 20 min, but imme- diately after they had been hauled on board the moth- ership Natsushima, the compound eyes of three individ- uals were fixed for 12 h at 4°C in 2% glutaraldehyde and 2% paraformaldehyde solution, buffered to a pH of with M cacodylate buffer. The dissections were car- ried out under dim red light to minimize further exposure to light and structural damage (cf. Meyer-Ro- chow, 1994). After a brief wash in buffer, the specimens were postfixed for 2 h in 2% OsO4 solution, using the same buffer as before, and dehydrated in a graded series of acetone before being embedded in Epon 812. Ultra- thin sections, cut with a diamond knife, were picked up on uncoated 200-mesh copper grids and stained with uranyl acetate and lead citrate for a few minutes. Obser- vations were carried out under a JEM 1200EX transmis- sion electron microscope, operated at 80 kV. Results In their external appearance the compound eyes of the deep-sea anomuran Paralomis multispina (Fig. Ib) re- semble those of other common anomuran shore-crabs (, genus Petrolisthes: Eguchi et 1982; Meyer-Ro-.
