Peter Wenker sent along this picture of a giant jellyfish. He doesn't think it's real, and I'd agree. I know that giant jellyfish do exist, such as the ones that recently appeared off the coast of Japan, but those were about the size of a washing machine, not the size of a truck. I've never heard of a jellyfish this big. So is this picture another product of Worth1000?

Update: Accipiter found a version of this same photo minus the diver, which would seem to indicate that the version with the diver has been photoshopped. (Unless it was the diver who was photoshopped out, but that seems very unlikely to me... [Wait a second, on a closer look it does seem that something might have been removed from the version without the diver. This will require more investigation.] ) The page he linked to also had some interesting jellyfish trivia, such as "The largest jellyfish ever found was a lion’s mane, with a bell 2m (7ft) across, and tentacles extending more than 35m" and "A collection of jellyfish is known as a smack."
