We've Hunted The Colossal Squid For 100 Years. It Keeps Winning.

We've filmed the surface of Mars and the bottom of the Mariana Trench. We have never filmed a healthy adult colossal squid alive at depth — an animal roughly the length of a small fire truck, with the largest eye ever measured in any animal. For a century we assumed it was rare. The evidence says otherwise. Sperm whale stomachs in Antarctic waters are full of colossal squid beaks, and something has to be feeding those whales. So the animal isn't missing. Our method was removing it from frame. This is the story of how bright lights, loud thrusters, and one very reasonable assumption kept a giant invisible for a hundred years — and how a silent camera, a fake jellyfish, and a wavelength no deep-sea eye can see finally started to change that. ⏱️ TIMESTAMPS / CHAPTERS 0:00 — The animal we've never filmed 1:10 — 1925: a species named from leftovers 2:24 — Why the whales say it isn't rare 3:32 — The twilight zone mistake 4:43 — The largest migration on Earth 6:10 — A 27-centimetre eye, and what it's actually for 7:17 — "Are vent shrimps blinded by science?" 8:08 — Everything else a submersible broadcasts 8:38 — The fix: far-red light and a very good lie 9:51 — March 2025: the first confirmed sighting 10:52 — Why the adult is still winning 11:52 — A hundred cheap eyes, and environmental DNA 13:18 — The instrument was never a neutral window 13:55 — What happens next 💬 JOIN THE DISCUSSION Two questions I'd like your answers to: What year do you think we finally film a living adult colossal squid? Drop the number — I'm keeping score. Where else do you think our instruments have been quietly editing the results? Deep sea, space, microbiology — I'll read every one.
