| Summary: | FIGURE 9. Antarctothoa ballia n. sp., NIWA 144835: A, biserial phase of ancestrulate colony along red-algal axis; B, mature phase showing near-maximum spread; C, F, autozooids, ovicellate zooids and male zooids (♂), showing the varied size of males, the left-hand one in F also showing rare frontolateral adventitious buds; D, tilted view of dimorphic combined maternal aperture and autozooidal aperture en face; E, H, a form of early astogeny, with budding of two daughter zooids displaced leftwards, the one asterisked curving round the algal stem axis; G, tilted (en face) view of male orifices showing the relatively large sinus; I, lateral view of ancestrula and daughter zooids; note how ancestrular right-lateral orificial tubercle pertains to daughter zooid; J, conventional astogeny, with neither daughter displaced, and with small gap between them mid-distal of ancestrular orifice; right-lateral tubercle pertains to ancestrula, the left-lateral one to the left daughter zooid.
