That's a big flippin' jelly fish.

Apparently, they're getting caught in nets and the fishermen are having to hack apart these 400 pound beasties to get at the few fish that are also in the nets. Suckage for the fishermen but it seems like finding a way to fish that would NOT entrap the jellyfish is the better option. I'm sure there's tons (literally! heh) of the jellyfish out there but it's a shame to kill so many.
