My niece Mollie and I are both jellyfish nuts (but not jelly donuts, as far as I know.) I definitely wouldn't want to come upon one of these 6 ft wide, 450 lb. creatures, though. I'm sure Mollie feels the same way. The giant jellyfish are terrorizing fisheries in China, South Korea, and Japan, killing and poisoning fish and breaking nets. It's wild to think of this sort of underwater life; it's like a whole other planet down there.
In nicer deep sea news, researchers recently discovered that mother squids nurse their eggs for months. It was commonly thought that all mother squids abandon their eggs immediately after laying them, so this was a surprising find (and a sweet one, too.)
