You've probably heard of the Portuguese man o' war. You know, the blue, floaty, stinging thing that'll ruin your day. It looks like a jellyfish, but it's actually no such thing. May I introduce you to the siphonophores, bizarre critters that can grow as long as a blue whale. Check out this week's episode of Absurd Creatures to learn more!
Big thanks to OET/Nautilus Live for providing footage.
Find every episode of Absurd Creatures here. And I’m happy to hear from you with suggestions on what to cover next. If it’s weird and we can find footage of it, it’s fair game. You can get me at matthew_simon@wired.com or on Twitter at @mrMattSimon.
