The Giant Pyrosome is a free-floating, colonial tunicate that is made of thousands of identical clones, together forming a hollow cylindrical structure that can be 60 feet (18 m) long and wide enough for a person to enter. Each individual clone is a small, complete animal that filters water, nonstop, in order to obtain food, flush out waste, and contribute to the propulsion of the entire super-organism. These clones have a notochord (“spinal” chord) and are therefore chordates, along with all vertebrates, including people. These comments from people first hearing about this mythical sea creature are hilarious. Also this dude rode one, yeehaw:
And here are some videos of the Giant Pyrosome:
