CONT

En général, les dents des Vertébrés ont une existence assez courte et sont remplacées de façon continue et pratiquement illimitée. La plupart des non mammaliens sont dans ce cas et [chacun] est dit polyphyodonte: les Sélaciens ont une centaine de dentitions successives, les Crocodiles une vingtaine. Les dents des Amphibiens sont remplacées à peu près tous les 6 mois.
