Fishermen based in Guaymas, Sonora, Mexico, brought in this massive great white shark. It was already dead when they encountered it; apparently it died after becoming entangled in the nets they had set for flounder.
As is usual in such cases, its size crept upwards as its image raced around the internet. Of the several websites I checked, the earliest had it at 5 meters--impressive, but hardly unprecedented. Others, however, are saying it's 6 meters long--nearly 20 feet. That would place it among the biggest great whites ever measured.
