Rhizocephala are derived barnacles that parasitise mostly decapod crustaceans, but can also infest Peracarida, mantis shrimps and thoracican barnacles, and are found from the deep ocean to freshwater. Together with their sister groups Thoracica and Acrothoracica, they make up the subclass Cirripedia. Their body plan is uniquely reduced in an extreme adaptation to their parasitic lifestyle, and makes their relationship to other barnacles unrecognisable in the adult form. The name Rhizocephala derives from the Ancient Greek roots ῥίζα (rhiza, "root") and κεφαλή (kephalē, "head"), describing the adult female, which mostly consists of a network of thread-like extensions penetrating the body of the host.

  • جذموريات الرؤوس (الاسم العلمي Rhizocephala)، رتبة عليا من القشريات الدنيا. فصائلها وأجناسها قليلة العدد. جميع أنواعها طفيلية. بعضها كالصقلين والبيغور يتطفل على القشريات أخصها عشريات الأرجل. أجسامها جرابية الشكل. دعاميصها فقط تتصف بصفات القشريات. (ar)
  • Les Rhizocephala sont un super-ordre de crustacés cirripèdes parasites dont les sacculines. Leur plan d'organisation est très réduit, témoignant d'une grande adaptation à leur mode de vie. Apparentés aux anatifes, ils leur ressemblent seulement sous leur forme larvaire. Adulte, ils ne possèdent aucun appendice, aucune segmentation visible, et tous leurs organes sont ancrés dans l'hôte, excepté les organes sexuels et la partie comprenant le système nerveux central.

  • Krabbezakjes (Rhizocephala) zijn parasitaire rankpootkreeften, die vrij algemeen wordt aangetroffen op vooral krabben, voornamelijk uit de zwemkrabbenfamilie (Portunidae), maar ook op andere tienpotigen. Langs de Belgische en Nederlandse kust wordt vaak de soort Sacculina carcini aangetroffen. (nl)
  • Rotfotingar (Rhizocephala) är en överordning i infraklassen rankfotingar (Cirripedia) bland kräftdjuren. Rotfotingarna är parasiter på andra kräftdjur, i de flesta fall tiofotade kräftdjur (Decapoda). Uppgifterna om artantalet varierar mycket; ITIS anger 68 beskrivna arter i 9 familjer. (sv)
  • 根头下纲(学名:Rhizocephala),原为根头总目 ,现升级为下纲。 (zh)
  • Rhizocephala é um grupo de crustáceos da classe Cirripedia (à qual pertencem os percebes e as cracas), que são parasitas de outros crustáceos, como os camarões e os caranguejos. Por esta razão, estes animais possuem adaptações que não permitem, à primeira vista, associá-los aos restantes crustáceos; de facto, é difícil sequer identificá-los como um ser vivo separado do seu hospedeiro. Um rizocéfalo (das palavras gregas que significam “raiz” e “cabeça”) adulto não tem apêndices, nem o corpo segmentado e perdeu todos os órgãos internos, com excepção das gónadas e resíduos do sistema nervoso. (pt)
