This Bird Has A Stomach Of Steel! #shortvideo #ostrich本站添加:
This bird is literally eating solid rocks. No, it hasn't lost its mind. This is actually a genius survival hack.
Ostriches are the biggest birds on earth, but guess what? They have absolutely zero teeth. Since they swallow everything whole like tough plants, seeds, and even small lizards, they need a serious backup plan. So, they swallow heavy stones to turn their gizzard into a biological blender. These rocks grind the food down so their bodies can digest it. In fact, a grown ostrich carries up to 2 lb of rocks in its stomach right now. Talk about a literal stomach of steel. Would you try the rock diet?
