They are fluid-feeding with a knoblike head provided with suckers and hooks, a short neck, and the rest of the body made up of a series of identical segments packed with reproductive organs. Larvae live within the gut vertebrates and arthropods, adults within vertebrates only, absorbing the hosts' food directly across their body wall; they reach a length of 40 feet in some species. ]]></termNote><termCreatedDate>2026-03-30 20:31:34</termCreatedDate><relation><relationType>UF</relationType><termId>31339567</termId><termName>cestode</termName><termType>ND</termType></relation><relation><relationType>UF</relationType><termId>31339568</termId><termName>cestodeans</termName><termType>ND</termType></relation><relation><relationType>UF</relationType><termId>31339569</termId><termName>tapeworm</termName><termType>ND</termType></relation><relation><relationType>UF</relationType><termId>31339570</termId><termName>tapeworms</termName><termType>ND</termType></relation><relation><relationType>BT</relationType><termId>31316296</termId><termName>Platyhelminthes</termName><termType>PT</termType></relation></term>  </Zthes>
