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.

On the nematocysts of hydromedusae [PDF]
Journal of the Marine Biological Association of the United Kingdom, 1938 The nematocysts of twenty species of Hydromedusae occurring at Plymouth are described. Of these, twelve were Anthomedusae and seven were Leptomedusae, and one was the Siphonophore, Muggiaea atlantica. The medusae fit very well into the generally accepted classification as regards the types of nematocysts they possess.

The Biological Bulletin, 1924 The nematocysts of Microstoma are derived from Hydra upon which Microstoma feeds. These ingested nematocysts are delivered to the mesoderm by the endoderm of the flatworm. Within the mesoderm an amœboid cell takes charge of each nematocyst and as it is transported to the surface orients it so that the "sting-thread" has its discharging pole directed ...

Latin American Journal of Aquatic Research, 2008 We performed qualitative and quantitative characterizations of the biological activity of nematocyst extracts from 30 specimens of Chrysaora plocamia collected off Huayquique, Iquique, Chile. After extracting the nematocysts from the jellyfish tentacles,
