Abstract Nematocysts of the scyphozoans Pelagia noctiluca and Rhizostoma pulmo were examined. In R. pulmo 4 types of nematocyst were observed: heterotrichous microbasic euryteles; holotrichous isorhizas; atrichous a-isorhizas; and atrichous α-isorhizas. In P. noctiluca 5 types of nematocyst were seen: heterotrichous microbasic euryteles; heterotrichous isorhizas (previously described as atrichous isorhizas); holotrichous O-isorhizas; atrichous a-isorhizas; and an undescribed type, which in its structure and discharge mechanism resembles microbasic p-mastigophores. The results show, in both P. noctiluca and R. pulmo, a greater variety of nematocysts than described in previous studies.
