dc.description.abstractThe large and small morphotypes of the medusa of Turritopsis nutricula McCrady were collected together for the first time, from lwaki City, Fukushima Prefecture, northern Japan, in 2004. The large morphotype had up t0 341 tentacles in three or four rows and an umbrella attaining up to 12.8mm in diameter and 12.1mm in heightja
dc.description.abstractthe females were brooding many planula larvae on the manubrium. The tentacular cnidome of the large morphotype consists of microbasic euryteles and desmonemes, the dimensions of which are given. The planula had only microbasic euryteles, the dimensions of which are also given.ja
dc.description.abstract福島県いわき市産の大型のベニクラゲにおいて,最大級の成熟クラゲ個体が雌雄で多数採集 され(最大傘径12.8mm,最大傘高12.1mm),その形態を精査したところ.これまでの記録であった2環列の触手ではなく通常3環列,まれに4環列となった新形質状態が確認された(触手数最大値341本).また,雌は口柄でプラヌラ幼生を保育することがわかった.クラゲのクニドームは2種類(microbasic eurytelesとdesmonemes)が触手にみられ,プラヌラのクニドームは1種類(microbasic euryteles)であったいわき市では,小型の成熟クラゲが大型のものと同時に日本では初めてのケースとして採集された.この小型の雌成熟個体の形態を測定し記載した.なお,大型の9個体の雌および7個体の雄は,いずれも若返りを起こさず消滅した.ja
