On the nematocysts of Æolids [PDF]
Proceedings of the Royal Society of London, 1904 While I was at Plymouth in July, 1902, Mr. W. Garstang suggested that I should investigate the origin of the nematocysts found in Æolids. He pointed out that no adequate account of their development had been published, and that the view held by some that they were derived from the Coelenterate prey of the Æolids had never been properly tested.

Force-dependent discharge of nematocysts in the sea anemone Haliplanella luciae (Verrill)
Biology Open, 2012 Summary Sea anemones discharge cnidae (‘stinging capsules’ including nematocysts) to capture prey and to defend themselves. In the present study, we tested the relationship between the force of test probes striking feeding tentacles and discharge of ...
