Polifiodonte

Crocodilo-do-nilo (*Crocodylus niloticus*)

Um polifiodonte é qualquer animal cujos dentes são continuamente substituídos. Diferentemente dos difidodontes que são caracterizados por ter apenas dois conjuntos sucessivos de dentes.^[1] Os polifodontes incluem a maioria dos peixes dentados, muitos répteis, como crocodilos e lagartixas,^[2]^[3]^[4] e a maioria dos outros vertebrados, sendo os mamíferos a principal exceção.
