FIGURE 3. Polydora tunicola sp. nov. Light micrographs showing the morphology of living (A–D) and fixed (E–I) specimens. A–D, F–I: paratypes (NSMT-Pol P-856), E: non-type larvae. A: anterior end, dorsal view. B: anterior end, lateral view. C: 2–11 chaetigers, lateral view. D: glandular pouches in the 7th to 14th chaetigers. E: larvae from a maternal tube. F: notopodial falcate spines and companion chaetae of the 5th chaetiger. G: neuropodial hooded hooks of 7th chaetiger. H: hooded hooks from neurochaetae of 20th chaetiger. I: hooded hooks from neurochaetae of posterior (60th) chaetiger. br—branchia; ca—caruncle; cc—companion chaetae; gp—glandular pouch; hh—hooded hook; lt—lateral tooth; ma—median antenna; fs—falcate spine; nec—neuropodial capillaries; nel—neuropodial lamella; noc—notopodial capillaries; nol—notopodial lamella; pa—palp; pr— prostomium; sh—shelf; vc—ventral capillaries. Scale bars: (A–D) = 1 mm; (E) = 300 μm; (F–I) = 50 μm.
