This may well be the world’s first-ever video of a bloody-belly comb jelly pooping! (Just in case anybody needed confirmation that Lampocteis has a through-gut. Also, it’s sparkly!!) Thanks to Aquarist MacKenzie for the video! | Monterey Bay Aquarium

Mesmerising, mysterious, and older than the dinosaurs — jellyfish have been drifting through our oceans for over 500 million years. They might look delicate, but they’re built for survival. Let’s make sure they’re floating through clean, healthy seas for the next 500 million. #Take3fortheSea #Jellyfish #OceanWonders #ProtectWhatYouLove #CleanOceans | Take 3

When grown-up jellyfish love each other very much, they make huge numbers of teeny-tiny potato-shaped larvae. Those larvae grow into little polyps that cling to rocks and catch prey with their stinging tentacles. But their best trick is when they clone themselves by morphing into a stack of squirming jellyfish pancakes. | Deep Look • PBS
