A29E36624B6C58088A85CE5C747CAB78.taxon	description	Description. External morphology. Parazoanthidae associated with host hexasterophoran sponge Pararete Ijima, 1927. Approximately 100 truncated cone-shaped cylindrical polyps in preserved specimen. Solitary or colonial polyps rise irregularly from host Pararete sponges (Figs 2 B, 3 D). The living and preserved polyps dark brown and tentacles brown in coloration. Ectoderm and mesoglea of capitulum encrusted with numerous and comparatively large sizes of sand and silica particles (approximately <100 µm). No encrustations of sand and silica particles in the ectoderm or mesoglea of scapus (Fig. 3 F). Contracted preserved polyps 3.0 – 10.0 mm in height, 2.8 – 5.0 mm in diameter. Capitulary ridges discernible when contracted, 15 – 16 in number, and 30 – 32 tentacles (Fig. 3 E).	en	Kise, Hiroki, Reimer, James Davis, Iguchi, Akira, Ise, Yuji, Tsuchida, Shinji, Fujiwara, Yoshihiro (2024): Parazoanthidae (Cnidaria, Zoantharia) associated with glass sponges on the Nishi-Shichito Ridge, northwestern Pacific Ocean, with the description of a new species.

79CE76E9E591569391B428BAD1978DAE.taxon	description	Description. External morphology. Colonial macrocnemic zoantharians associated with host hexasterophoran sponge Farrea Bowerbank, 1862 (Fig. 2 A). Solitary or colonial polyps rise irregularly from all over the three-dimensional structure of host hexasterophoran sponge with base of polyps embedded in tissue of sponge (Fig. 3 A). Preserved specimens consist of cylindrical polyps (Fig. 3 B, C), dark brown in coloration. The living polyps and tentacles transparent yellowish in coloration. Surface of column smooth and ectoderm continuous (Fig. 3 C). No encrustations of sand and silica particles in ectoderm of capitulum but ectoderm of scapus encrusted with small-sized sand and silica particles. Contracted preserved polyps 1.5 – 2.5 mm in height, 1.0 – 2.5 mm in diameter. Capitulary ridges indiscernible when contracted. Tentacles 22 – 26 in number. Internal morphology. Zooxanthellae absent. Cyclically transitional marginal musculature (Fig. 4 A – C). Encircling sinus or mesogleal canal present and basal canals of mesenteries absent (Fig. 4 E). Mesenteries 22 – 26 in number, in brachycnemic arrangement (Fig. 4 D). Mesoglea thickness 20 – 30 µm. Siphonoglyph distinct and V-shaped. Mesenterial filaments present. Complete mesenteries fertile (Fig. 4 E). Cnidae. Basitrichs and microbasic b-mastigophores, microbasic p-mastigophores, holotrichs, special b-mastigophores, and spirocysts (see Fig. 5, Table 1 for sizes and distributions).	en	Kise, Hiroki, Reimer, James Davis, Iguchi, Akira, Ise, Yuji, Tsuchida, Shinji, Fujiwara, Yoshihiro (2024): Parazoanthidae (Cnidaria, Zoantharia) associated with glass sponges on the Nishi-Shichito Ridge, northwestern Pacific Ocean, with the description of a new species.
