I am thinking a 61 ton fish living in cold water needs to eat at least a thousand pounds of protein and fat every day.
Roughly, that would be 120 cans of tuna fish every hour - with no breaks.
In addition to swallowing a Great White shark whole, I noticed they said Megalodon could gulp down a modern Killer Whale in just five bites! So for Megalodon, a killer whale would be like, what?, a Big Mac to us? Can't say I'm sorry those things went extinct!
But would he recycle the cans?
I hope they can find some DNA and revive them. One of them would feed half of Japan.
