That's insane. How are those not extinct? They're massive, slow, and I can't see how they can defend themselves. Unless they just live far outside predatory areas I'd expect them to just be floating buffets for sharks and such.

Wow...that thing is huge! Hard to even comprehend.

Here some more information, and part of the reason why they arent extinct:

Sunfish live on a diet consisting mainly of jellyfish, but because this diet is nutritionally poor, they consume large amounts to develop and maintain their great bulk. Females of the species can produce more eggs than any other known vertebrate. Adult sunfish are vulnerable to few natural predators, but sea lions, killer whales, and sharks will consume them.

Also humans haven't found a way to populate the oceans yet.

or figure out how to make sunfish taste worth a damn.
