Blue whales are actually indeed much larger than the largest dinosaur.
Far bigger than any dinosaur, the blue whale is the largest known animal to have ever lived.
An adult blue whale can grow to a massive 30m long and weigh more than 180,000kg - that's about the same as 40 elephants, 30 Tyrannosaurus Rex or 2,670 average-sized men.
Blue whales are the largest animals that have ever lived they're even bigger than dinosaurs!
Blue whales can grow and reach 34 meters (110 feet) long and weigh as much as 172,365 kilograms (190 tons).
The biggest thing a whale could swallow without chewing it up is something the size of a grapefruit.
Anything larger than a grapefruit then the whale could not simply swallow it without chewing it up first.
Although a whale is pretty big and has a pretty big mouth they could not actually swallow something too big.
A Whales mouth might be large but the whales throat where it swallows things and food is about the size of a small salad plate.
The biggest thing that a whale could actually swallow would be a grapefruit or anything the size of a grapefruit.
If whatever it is that the whale is trying to swallow is larger than a grapefruit then they would not be able to swallow it.
I've heard of cases and stories where whales swallowed a human but that would actually be impossible and if you did get swallowed by a whale you would likely die due to the digestive acid in the whales stomach.
There was a story about some guy being swallowed by a whale years ago and supposedly lived to tell the tale but I believe that's all it was is a tale which was made up.
Unless that whale had a huge throat then a human would not be able to get down the whales throat.
