The crocodile has a aerodynamic design in body. It's hard bumpy skin works similar to a Golf ball in the way that the low pressure areas of the pitted skin allow faster smoother movement without sound.
The crocodile is also very low to the ground when it wants to be and can easily slide into the water. They also are able to move their liver to distribute buoyancy thus able to only show their head above water and create less surface disturbance and less sound.
The art of the crocodiles movement is all about stealth and speed thus evolution designed them to be silent killers.
They stalk their prey noiselessly and attack them at the right opportunity.
Oh yes, crocodiles move around.
The sapper noiselessly cleared the open field and began setting his explosives. The owl noiselessly swooped down upon the hapless vole.
they have feet
noiselessly, soundless
They haven't got one.
Much the same as alligators and crocodiles do.
no. crocodiles can not move there tongues.
Silently Softly Gently Soundlessly Noiselessly In silence
Their tongue. (Snapple Fact #132)
Faintly, inaudibly, murmuring, noiselessly, softly, soundlessly, tacitly, weakly
No, crocodiles are not fish. Crocodiles are reptiles.
