Nematocysts of the coronate scyphomedusa,Linuche unguiculata, with a brief reexamination of scyphozoan nematocyst classification

  • Dale R. Calder
Short Papers and Notes


Nematocysts were examined in specimens of the coronate scyphomedusaLinuche unguiculata collected off the North Carolina coast. The cnidome consisted of isorhizas and heterotrichous microbasic euryteles. The isorhizas were all of the a-isorhiza variety; euryteles were present in small and large size classes. Changes in the classification of scyphozoan nematocysts are discussed, and the terms “a” atrich, “A” atrich and “α” atrich are changed respectively to a-isorhiza, A-isorhiza and α-isorhiza.
