Microbasic p-mastigophores, euryteles of two size groups, holotrichous isorhizas and atrichous isorhizas, comprise the cnidom of Chironex fleckeri, a cubozoan that has been responsible for several human fatalities. In its undischarged state each microbasic mastigophore of C. fleckeri consists of a capsule containing matrix and an inverted tube possessing a smooth-walled butt which is loosely coiled helically and which narrows to form a thread that is tightly coiled helically and markedly pleated. Both butt and thread carry three helices of spines and contain a granular matrix. During discharge, the proximal butt spines form initially a piercing stylet. Granular material from the butt and thread is released prior to the release of capsular material. Each eurytele possesses a tube with a butt composed of three bulbs, the middle bulb bearing long spines. Each holotrichous isorhiza possesses a coiled tube bearing small spines along its length. Each atrichous isorhiza exhibits a tube that is devoid of spines and loosely folded in the undischarged condition. The probable role of each type of nematocyst is inferred from its structure and features that enable the ready separation of the nematocysts of C. fleckeri from those of scyphozoan jellyfish are discussed.
微基刺丝囊、两种大小组别的宽刺丝囊、全毛等刺丝囊和无刺等刺丝囊，构成了箱形水母——费氏手曳水母（Chironex fleckeri）的刺胞囊，该水母已导致数起人类死亡事件。在未发射状态下，费氏手曳水母的每个微基刺丝囊由一个包含基质的囊和一个倒置的管组成，该管具有光滑壁的柄部，柄部呈松散的螺旋状盘绕，并且变窄形成紧密螺旋状盘绕且明显褶皱的丝。柄部和丝都带有三排刺螺旋，并含有颗粒状基质。在发射过程中，近端柄部刺最初形成一个穿刺针。在囊材料释放之前，柄部和丝中的颗粒物质会被释放。每个宽刺丝囊都有一个带有由三个球茎组成的柄部的管，中间的球茎带有长刺。每个全毛等刺丝囊都有一个沿其长度带有小刺的盘绕管。每个无刺等刺丝囊都有一个无刺的管，在未发射状态下松散折叠。从其结构推断了每种刺细胞的可能作用，并讨论了能够将费氏手曳水母的刺细胞与钵水母纲水母的刺细胞轻易分离的特征。
