Outline of Final Research Achievements

The author made detailed observations of the morphology and development of Cubozoa, Chironex yamaguchii. This study revealed: 1) seasonal occurrence of C. yamaguchii in Okinawa, 2) settlement selectivity of planulae, 3) morphological changes of medusae with growth, 4) cubozoan diversity in Southeast Asia. Chironex yamaguchii has sexual, planktonic medusae and asexual, benthic polyps
in their life cycle. Complete metamorphosis of a whole polyp into a single medusa occurred. Undescribed species of Chironex inhibit in Southeast Asia.

Academic Significance and Societal Importance of the Research Achievements

沖縄に生息する箱虫綱の一種ハブクラゲは致死的な刺傷被害をもたらすため、公衆衛生上の大問題となっている。そのため、本種の刺傷被害対策が急務とされている。また、箱虫綱の生活史はほとんど知られていないため、底生世代であるポリプと浮遊世代であるクラゲが互いに別種とされるような混乱が起こっている。本研究では、ハブクラゲの生態学的および分類学的研究を進め、本種の季節的消長や出現動態、生活史、東南アジアにおけるハブクラゲ属の多様性を明らかにした。本研究により得られた成果は、ハブクラゲの防除や箱虫綱の分類学的整理の基盤となるものである。
