Flögudýr (Placozoa^[3]) er fylking sjávardýra sem lifa sjálfstætt (ekki sníkjulífi).^[4] Þau eru samsett úr einfaldri þyrpingu fruma, án sérstakra líffæra eða líkamshluta. Þau nota bifhárahreyfingu til að færa sig til í vatni, nærast með agnaáti þar sem þau umlykja fæðuna, og fjölga sér með klofnun eða knappskotum. Þeim hefur verið lýst sem einföldustu dýrum jarðar.^[5] Sameindagreiningar styðja þá kenningu að flögudýr séu einföldustu dýr jarðar,^[6]^[7] og frumstæðasta fylking vefdýra.^[8]
