Abstract: Rejuvenation is induced by body damage by means of needle sticking of senile female and male medusae of Turritopsis sp. (Hydrozoa, Anthomedusae) collected from Shirahama, Wakayama Prefecture, Japan. As a result, stolon-extention rejuvenation took place in both species (60, 40%, n = 5 respectively), but zooid-formation rejuvenation rate is very low (10 %, n = 10). This rate is lower than that of very young medusa (83.3%, n = 12) from the same locality, suggesting that senile individuals are difficult to accomplish a complete rejuvenation.
和歌山県白浜産のニホンベニクラゲ(ヒドロ虫綱,花クラゲ目)の老衰した雌雄5個体ずつを針で突いて体に損傷を与えて若返りが起こるか調べた.その結果,雌雄はそれぞれ60%と40%の率で若返りを示したが,個虫まで形成できたのはわずか10%(n = 10)であった.完全な若返りは,同じ白浜産のごく若いクラゲの若返り率(83.3%, n = 12)より相当低かったことから,老衰個体は若返りを実行し難いことが示唆された.
