Most jellyfish have in common a rounded, nearly transparent gelatinous body with a mouth on the underside surrounded by stinging tentacles; their bodies alternately expand and contract, allowing them to trap prey in their tentacles as they jet upward and parachute down again. ]]></termNote><termCreatedDate>2026-03-30 20:31:35</termCreatedDate><relation><relationType>UF</relationType><termId>31339626</termId><termName>jelly-fish</termName><termType>ND</termType></relation><relation><relationType>UF</relationType><termId>31339627</termId><termName>jellyfishes</termName><termType>ND</termType></relation><relation><relationType>BT</relationType><termId>31316338</termId><termName>Cnidaria</termName><termType>PT</termType></relation></term>  </Zthes>
