They swallow stones that aid digestion and help them swim, since they naturally float.
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.
Yes they do
No it is not. Crocodiles are unable to stick out their tongue because they swallow rocks to help them dive deep without floating up. All the rocks make it impossible to stick out a tongue.
can they dive deeper than a nother bird? yes they can
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.

Yes, deeper can be an adverb. (e.g. dive deeper) However, the equivalent adverb "more deeply" is sometimes appropriate.
Crocodiles don't generally dive, the slide into the water from a bank and swim close to the surface to break for air.
Recreational divers usually don't go any deeper than 60ft. The recreational dive limit is 130ft.
Alex went deeper into a trance at the sound of the bell. My last dive was 75 feet deeper than the first.
Its farther from the surface where the sun reflects.
