Which was totally cool with the lungfish; after the team added a little water, it popped right back to life -- perfectly fine in every respect.
They buried it alive without air or moisture for six months and couldn't kill it. If Hollywood has taught us anything, that's enough motivation for the lungfish to don a sinister cloak and start killing teenagers with a hacksaw.
Scientists have a habit of giving animals names that take certain liberties (for example, they might see that something has "skin" and call it a bear, because bears also have skin,) but this time science was telling us the facts straight up: Immortal jellyfish do not die. Ever.
Great! So How Do I Kill It?
The immortal jellyfish are born, develop and reach full maturity like any other gelatinous spawn of the ocean. However, instead of going to the Great Barrier Reef in the sky at the end of life, they simply revert back to a polyp (that's fancy Water Science talk for "baby"). In theory this could go on forever. Right now you're probably feeling a little gypped by this entry: "In theory? Lame! I guess it was unreasonable of me to expect something on Earth to literally live forever, though."
Nah, we're just fucking with you: They're totally immortal, which is resulting in a giant influx in the jellyfish population. Millions of years ago, the first of these jellyfish was born, and somewhere in the ocean it's still living today.
"Get out of my way, you young punks!"
Our only hope is that when two immortal jellyfish get together they have to swordfight to the death because "there can be only one." Otherwise, we all better practice breathing gelatin because it's gonna get straight Jellyfish up in here.
