利用扫描电镜对尸体囊藻（Sacculinacarcinii）四无节幼体进行了形态学研究。额角和整个发展的典型无节幼体四肢保持简单和缺乏gnathobases。这些特征是其他卵磷脂营养型藤壶无节幼体的特征。一个退化的腹侧胸突的存在是明显的第III阶段无节幼体，甚至更突出的第IV阶段无节幼体。这些观察结果证实，根头类无节幼体是接近thoracican无节幼体的形式，并提供强有力的支持，保留根头类内的蔓足类。
A morphological study was carried out on the fournaupliar stages of Sacculina carciniusing mainly scanning electron microscopy. Frontal horns were present and throughout development the typical nauplius limbs remained simple and gnathobases were lacking. Such features are characteristic of other lecithotrophic barnacle nauplii. The presence of a vestigial ventral thoracic process was evident on the stage III nauplius and was even more prominent on the stage IV nauplius. These observations confirm that the rhizocephalan nauplius is close to the thoracican nauplius form and lend strong support for the retention of the Rhizocephala within the Cirripedia.
