I can't explain it, I'm fascinated by ALL creatures big and small...even the prehistoric megalodon (which for those of you who don't know was a giant shark big enough to swallow a few blue WHALES whole)
A quick correction here:
The Megalodon (usually
Carcharodon megalodon) is generally believed to be a larger prehistoric relative of the great white shark (
Carcharodon carcharias). Megalodon is mostly known from fossilised teeth as well as some vertebrae. By extrapolating a skeleton from this size the current estimates are a creature that would grow up to 17 metres depending on whose research you read (giving a body weight of around 45,000 kg).
The Blue Whale (
Balaenoptera musculus) has been recorded at lengths of up to 33 metres (though scientists have only measured up to 29.9m) and weights of at least 177,000kg, so around twice as long and four times as heavy as the Megalodon.
Blue Whales are believed to be the largest creature to ever have lived, so it is unlikely anything can swallow a few of them whole, unless one is discussing newborn calves.
