eels must open and cloth their mouths constantly in order to circulate water over their gills
They eat through their mouths.

I am pretty sure moray eels eat shrimp because I've seen pictures with shrimp in their mouths
The temporomandibular joint (TMJ).
Frogs open and close their mouths to breathe. They don't have diaphragms to help them breathe, so they use muscles in their mouth to push air into their lungs. They also use this action to help them swallow food.
No. If they didn't open and close their mouths, water couldn't flow through their body, and then out their gills. Thus, they wouldn't survive.
No. Crocodiles have muscles in their mouths that are extremely powerful, and designed to firmly. When submerging under water, they close their ear and nostril flaps. They have a third eyelid, called the nictitating membrane that protects their eyes underwater.
to eat, or to sing, or to vomit into the mouths of their children
Crocodiles are often seen on the beach, looking like they are asleep, with their mouths open. What they are doing is basking, they keep their mouths open to regulate their body temperature. People sweat, dogs and cats pant, and crocodiles open their mouths :)
from what i know, snipe eels eat shrimp. they swim along the ocean with their mouths open. they have tiny, hooked, backward facing teeth on their jaws that snag onto the antennae of the shrimp. the shrimp are then moved inside the mouth, eaten, and digested.
yes
they open their mouths' and just wait until some krill or plankton, or other small sea creatures come by then they just clamp there mouths' shut and eat what ever is in there mouths' and then they just keep on this process
