論Anthopleura elegantissima 海葵浮浪幼蟲刺細胞之顯微構造

On the Fine Structnre of the Nematocysts in the Planula Larva of a Sea Anemone, Anthopleura elepgantissima

Anthopleura elegantissima 海葵三週大之浮浪幼虫具有五種刺細胞，其中四種( atrichs, bastrichs, microbasic, p-mastigophores 及 spirocysts) 存於外胚層，二種( microbasic p-mastigophores 及 basitrichs )則存於內胚層纖維中。五種刺細胞之顯徵構造在文中已有敘述，至於浮浪幼虫外胚層內刺細胞之豐度( aboundance )、分布( distribution )與抵禦浮游性捕食者及著生附著之關係亦於文中一併討論。
