|Some facts on a crocodile's mouth:|
The bony palate in a crocodile's mouth separates its nasal passage from its mouth. A valve at the top of the crocodile's throat keeps water out of the airway, allowing it to hide underwater as long as its nostrils stay above the surface. (I think we cans ee the valve in the pic) With only its nostrils protruding from the water, a crocodile stays well hidden. A crocodile can also hold its breath under water for up to two hours
Crocodiles also have special glands in their tongues that can get rid of excess salt, so they tend to live in saltwater habitats.
It is easy to hold a crocodile's mouth shut the muscles that open them are much weaker than those used for snapping them shut.
Crocs mouths can close with a pressure of 4000psi and it takes about 200-300psi to break a human bone.
For such ancient, ferocious-looking animals, crocodilian moms take really good care of their hatchlings! Crocs are one of the few reptiles that watch out for and protect their young until they are old enough to be on their own. The cow (female croc) looks for just the right place to build a nest to lay her eggs.
Some species make a mound nest out of soil and vegetable material; others dig a hole in the sandy beach for their nest. The mama croc then settles in nearby to guard the eggs from predators that might try to dig them up and eat them. When the babies are ready to hatch, they make grunting or barking noises from inside the egg, and use a short little tooth on the end of their snouts called an “egg tooth” to start breaking out of the leathery shell. Some croc moms even help by gently biting the egg to open it up more easily.
After the young have hatched, the mom carries them to the water in her mouth (except for gharials, which have mouths that are too narrow), then guards them for most of the first year of their lives. Sometimes the hatchlings get to ride on her back, too. She will threaten or attack any predator that lurks too close, and in some species she will call the hatchlings to swim into her mouth for protection—making it look like she's swallowed them!

Wow, what a big mouth !!!
Fantastic POV that gives us a real close view of the interior of this formidable part of this huge reptilian. I am surprised your hands were not shaking.
Is this an alligator or a crocodile? TFS. : )
It's a big mouth! Great idea, details, note and composition!
