Черепахи и крокодилы, как и все пре­смыкающиеся, являются настоящими на­земными позвоночными, несмотря на то что многие из них обитают в воде. Все они имеют сухую ороговевшую кожу, практи­чески лишенную желез. Кроме того, у них характерное для пресмыкающихся стро­ение опорно-двигательной, кровеносной, дыхательной, нервной, выделительной и репродуктивной систем органов.
