What BBN said about it

Hank Ledger · Lead AnchorA dwarf reed snake, when threatened, does not slither away. It cartwheels. Popular Science reports it was filmed in slow motion.

Vera Bullock · Co-AnchorIt's a snake under twelve inches long, Hank. Researchers at Japan's Toho University filmed it with a high-speed camera.

Hank Ledger · Lead AnchorUnder twelve inches, and it has abandoned the ground. The retreat is now about one foot per second, four times faster than slithering.

Vera Bullock · Co-AnchorFour times faster than slithering. So it's a very slow snake that found a better way.

Hank Ledger · Lead AnchorScientists first shared snapshots of this in 2023. That means the snake has been rolling for years and we were not informed.

Vera Bullock · Co-AnchorInformed by whom?

Hank Ledger · Lead AnchorIn the lab, Science News says, the snakes tumbled at six to thirteen kilometers per hour on a two point two meter racetrack.

Hank Ledger · Lead AnchorA racetrack, Vera.

Vera Bullock · Co-AnchorWhich they only used after being tapped. Gently. That was the whole threat, a gentle tap.

Hank Ledger · Lead AnchorSo the most dangerous thing in that lab was a researcher with a finger.
