摘要
Aglantha perform regular "fishing" cycles, swimming up with tentacles contracted, and floating down with tentacles extended. The upward orientation of the swimming phase depends on input from the statocysts. In a 2-m tall tank, Aglantha showed a migration pattern toward the surface during the day and away at night. Slow swimming in Aglantha involves graded, nonpropagative muscle responses. Input from the tentacles is excitatory, and from conducting epithelia inhibitory to slow swimming. The nervous pathways mediating slow swimming are distinct from the giant axons mediating fast (escape) swimming described in earlier papers. There is no protective "crumpling" response.Key words: jellyfish, swimming, statocyst, vertical, migration, diurnal, zooplankton, hydromedusae, pacemaker, escape

Aglantha定期进行钓鱼活动，游泳时触手缩小，并用触手向下漂浮。游泳阶段的向上取向取决于来自静脉的输入。在一个2米高的坦克中，Aglantha在白天向远离地面显示出一种迁移模式。在Aglantha慢游泳涉及分级，非传导性肌肉反应。来自触角的输入是兴奋性的，并且从上皮抑制到缓慢游泳。调节缓慢游泳的神经通路不同于早期论文中描述的调节快速（逃逸）游泳的巨型轴突。没有保护性的皱纹反应。关键词：水母，游泳，静脉，垂直，迁移，昼夜，浮游动物，水蛭，起搏器，逃生
