Do sharks really growl? Final Answer!
This is for everyone who hates this scene! There is really no point in finding this info because it obviously won't change what happened in the movie but what the hell...here you go!
Do Sharks Make Sounds?
Pioneer undersea explorer Jacques Cousteau called the ocean realm the "Silent World", but nothing could be further from the truth. Whales sing haunting songs, dolphins yap and click, snapping shrimps crackle like castanets, and teleost fishes produce all sorts of grumbles, burbles, grunts, croaks, buzzes, and clicks. But, although they are very much attuned to this great oceanic opera, sharks are — by and large —the quintessential silent hunters.
Unlike their noisy neighbors, sharks have no organs for producing sound. Even their scales are modified to allow them to slip through the water in ghost-like silence.
