30+ foot huge shark caught in china, article says its a blue shark but its obvious to me that its not. blue sharks dont get that big, not even close. most sources ive found suggest its really not likely to get bigger than 12 or 13 feet.

this is a real blue shark, my favorite kind of shark. they just look cool. plus they hunt like wolves. and they are probably the smartest sharks in the ocean.

megalodon jaws. if one of these existed today that would be ridiculous to see. btw scientists havent been able to prove that there are none left, as a few might have survived in depths we cant reach yet.
