| Research Abstract |
During the comprehensive analyses on metazoan development, significant results were obtained in particular from placozoans and Xenoturbella. For placozoans, a reliable collection method was established and preliminary data on its reproductive cycle have been obtained. I have also succeeded in keeping placozoans in lab, and asexual reproduction by division was observed. Xenoturbella was found to belong to a fourth phylum within the deuterostomes, and ultrastructural studies were performed on its sperm and larvae. New implications on the diversity and evolution of metazoan development were acquired from these results.
