The experts say:The size is exaggerated.
How Realistic Are Shark Attacks in Movies?

Every living shark, except for a handful of species, have five gill slits.
They made them flutter very prettily thats actually what made me notice, Whats going on with this?
That bothered me the whole time.

Like, just get in there barefoot?)
A very, very small whale, like a dolphin or something like that, sure.
[But] theres no doubt that they ate whales.

As for whether Meg could have cleanly devoured that cage?
So if you ramp up the length of the shark and its jaw size, its conceivable.
When you go to the dentist and theyre working in there, thats why they have the sucky thing.

It would have had to close its mouth completely with the cage inside to swallow that.
The experts say:First of all, Jonas & Co. would have needed a bigger boat.
Some estimates of megalodons weight rival that of the blue whale, at 100 tons.

In the movie world, sure, driving by and splitting it open is possible, Ehret says.
Theyre not hovering and watching this big fight going, Whos gonna win?
like in high school or something, Whitenack says.
Theres not that many sharks in that area usually.
The experts say:Megalodon is definitely extinct (sorry,conspiracy theorists).
It wasnt a deep-water shark, Ehret says.
The idea that Meg was hiding in the Marianas Trench is just not plausible whatsoever.
I get that question almost every day.
