No. But crocs (like some birds) may swallow a few stones to help with breaking down the food into digestible pieces.. Crocs can't chew their food, they only rip lumps off and swallow.
Crocodile's swallow stones so they can dive deeper. They can hold there breath for up to 1 hour depending on how old they are.
They swallow stones that aid digestion and help them swim, since they naturally float.
Crocodiles don't generally dive, the slide into the water from a bank and swim close to the surface to break for air.
Crocs don't breathe underwater. They have lungs and Breathe air pretty much just like you and I. They hold their breath when they dive.
