What about you?
Do you believe any of these animals really exist? Why/Why not?
Yeti, Loch Ness Monster, Bigfoot, Mokele-mbembe, Pterosaur... any others?
From my point of view these kind of animals... could have been exist... but not as the same definition as has arrived nowadays... I think that there some animals that through the popular culture has exaggerated its definition.
For example the yeti, maybe there was a big animal in the Himalayas mountains but people might have exaggerated because of the ignorance and so on.
