The Most Annoying Australian Import Since Yahoo Serious.

Jellyfish stump scientists
This time, scientists say, they may not just be visiting

Nothing new on the Dreaded Snakehead front, but we have this from the Gulf of Mexico on spotted jellyfish, the Australian species that showed up a couple of years ago. It looks like they've established themselves off the Gulf Coast, and that we're just going to have to put up with them from now on. (Another population is showing up off Atlantic coast of Florida.) You know the drill -- unchecked population, no natural predator, local species outcompeted. They hunt young fish and shrimp, which isn't good for the fishing industry, to say the least.
