Crocodiles Going Feral At B-Flat (Actually: American Alligators)
In the 1940s, crocodiles—after being observed to react by chance to a specific note produced by a tuba—would begin a distinctive dance the moment they heard it. This display, tied to the release of sexual instincts, is also a fascinating example when viewed through the lens of music’s universality.
There’s this thing where “crocodiles” (more accurately, most of the time American alligators) hear a certain low note and instantly switch into: “I’m the biggest, meanest male in this place!” mode.
I’m not exaggerating. Everything’s calm, the water is flat, then someone hits a thick B-flat… and the animal lifts its head, puffs up, vibrates, and the surface starts doing that weird “water dance” like the swamp itself is reacting.
So How Was This Discovered?
This is the best part.
The story goes back decades: people noticed that a large captive alligator reacted strangely to certain sounds, and at some point (in the classic version of the tale) different instruments get tested—until B-flat triggers the full display: bellowing, body inflation, that “I’m here” dominance posture. It’s often told as one of those museum-lore anecdotes involving an alligator named Oscar. (It shows up in long-standing retellings rather than as a clean “paper citation” moment.)
What’s The Real Reason? Mating + A Challenge Signal
This is not “music theory” in an alligator’s brain.
To the animal, that low frequency doesn’t register as a note. It registers more like:
“Is there a stronger male around here?”
Or even: “Someone is broadcasting dominance—do I need to answer?”
So the response package makes perfect sense:
-
Head up, posture changes
-
Body inflation / vibration
-
Bellowing
-
And sometimes the iconic Water Dance—ripples and tremors on the surface as the animal vibrates and pushes sound/energy through the water.
Do People Actually Go Out And Play Music By The Water?
Yes. And not just as a meme—there are real demonstrations where someone brings a tuba (or plays low tones) and the alligators respond exactly the way you’d expect: they size up, posture, and start calling back.
The Part That Really Got Me
People say “music is a universal language” all the time, and it’s usually just a cute line.
But here it becomes weirdly literal.
Because what we call a “note,” the alligator experiences as a biological message:
“I’m here.”
“This is my territory.”
“I’m the male you have to deal with.”
One low B-flat and you can basically flip a switch in a prehistoric animal’s wiring.
And that… is honestly insane.
