Each crocodile has 24 teeth in its powerful jaws, which are constantly replaced throughout its life. However, these teeth are designed to grab and crush prey, rather than chew it. The reptiles swallow stones, which grind up food in their stomachs.
每條鱷魚在它強(qiáng)有力的下顎內(nèi)都藏著24顆牙齒。這些牙齒在其整個(gè)生命中不斷更新。然而, 這些牙齒完全是用來撲捉和粉碎獵物的，不是用來咀嚼的。這種爬行動(dòng)物往往吞石下肚，然后靠這些石頭來幫助磨碎胃中食物。
