Jellyfish

 * ... that jellyfish are the source of green fluorescent protein that has been used as a fluorescent marker of genes inserted into other organisms?
 * ALT1:... that jellyfish can disable power stations?

 * Symbol question.svg Article is a new GA, long enough, and well written. I find the main hook more interesting, and it's verified with a reliable source. QPQ is done. There is some minor close paraphrasing issues including verbatim phrases "roamed the seas for at least 500 million years" and "feeding on plankton, crustaceans, fish eggs, small fish and other jellyfish". Please see Earwig report for details. And why not a picture? -Zanhe (talk) 22:26, 18 October 2018 (UTC)
 * I have rephrased those passages. I thought the image for the green fluorescent protein species was unsuitable and I didn't know what species had brought power plants to a halt, but I rather like ALT1, with its implications of jellyfish turning off the lights.

 * Thanks for the edits. There's still one more paragraph under "locomotion" too closely paraphrasing the Nature source: "the second vortex ring rolls under it and begins to spin faster. This sucks in water which refills the bell and is pushed up against the centre of the body, giving it a secondary and "free" boost forward. The mechanism, called passive energy recapture, only works at low speeds and relatively small body sizes". Source: "the second vortex ring rolls under it and starts to spin faster. This sucks in water, which pushes up against the centre of the jellyfish" and "the jellyfish's technique works only at low speeds and relatively small body sizes". -Zanhe (talk) 21:53, 19 October 2018 (UTC)
 * That's what happens when you start improving a pre-existing article and leave some of the text intact. Is it OK now? Cwmhiraeth (talk) 10:00, 20 October 2018 (UTC)
 * Symbol confirmed.svg That's understandable, and thanks for fixing the issues. Looks good now. Both ALT0 and ALT1 are verified and good to go. -Zanhe (talk) 18:49, 20 October 2018 (UTC)
