Figure 7
A schematic drawing suggesting the life history and young polyps of an extant viviparous species.
A, The fossils demonstrate asexual proliferation by two-round transverse fission. Transverse fission may occur in the juvenile and adult stage. The stalk-like pedicle of the holotype and a paratype also implies sexual life cycle of the animal. B, Young polyps obtained from the gastric cavity of an extant actinostolid actiniarian species from 192–250 m in depth. Scale bar, 0.2 mm.
