Key Questions Answered

The stones that crocodiles swallow and reach their stomachs are known as gastroliths, which play a very important role in their digestive system by acting as a natural grinding tool to break down food.

Because crocodiles swallow their prey in large pieces without chewing it completely like humans, the stomach stones mechanically break down the food into smaller pieces, while strong gastric acid helps dissolve bones and hard materials.

While the extra weight from the stones may help control body stability and buoyancy in water, it cannot be definitively said that crocodiles swallow stones solely to go deeper, as aiding digestion is considered one of their main functions.
