Those first couple pics definitely look fake to me, I know some jellyfish can be very long, but what I'm not sure about is how big that can be in diameter.

the massive jellyfish pic is definately a fake. done in photoshop. I am a photoshop tutor and the obnoxious teenagers i teach could easily produce something as realistic. the diver a different res than rest of pic.
I not saying that something like that dont exist though. Just not in this pic.
happy swimming y'all.

Where is the film of this thing, the diver does have a camera right?

Kitsunegari says:

"box jellies are more dangerous, not just because of their potent venom, but also for the fact that they are the only jellyfish with eyes and brains. plus the fact that they actually swim, not only drift with the current."

That is not true.

Cubozoans (box jellies), like all cnidaria, do not have eyes and brains. As a matter of fact, cnidarians (which include coral polyps, anemones, and jellies) do not even have organs, only tissues. There are three layers of tissues in cnidaria: ectoderm on the outside, gastroderm on the inside, and mesoglia which is the 'jelly'. (The stinging nematocysts are merely specialized ectoderm cells)

The only multicellular animal simpler than cnidarians is the phylum porifera, or sponges, which only have a cellular makeup.

The "next up" marine phylum, platyhelminthes (flatworms), are the first animal to actually have organs and organ systems.

Furthermore, many cnidarians, especially the medusae forms as opposed to the polyp forms, are motile and can control their movement to some extent.

The Jellyfish is in color with no underwater distortion, easily debunked. The diver was truely in the picture, and the Jelly fish is probably pasted over top of a shark or something...

The least the hoaxer could have done was add some blue tint to the Jellyfish to make it at least appear to be undewater.

that's an image (talking about first pic in thread) from the worth1000.com photoshop contests site....
