Scientists Discover Why Snake Embryos Twist Into Spirals

Baby Snakes Spiral As Embryos. We Didn’t Know Why, Then Scientists Discovered A Structure We Had Never Seen In An Animal Before

“This is a nice reminder that in biology there is still so much to discover by just looking.”

Scientists discover why snake embryos twist into spirals

Snake embryos begin life curled into a distinctive right-handed spiral, and scientists may finally know why. Their bodies grow faster than their guts, creating a tether that forces the lengthening embryo to buckle and twist inside the egg. Researchers reached the conclusion after studying more than 900 embryos and using CT scans to reveal the hidden anatomy behind the coils.

The Mystery of Why Snake Embryos Curl To The Right Could Lie In Their Digestive Tract

Learn how a slower-growing gut helps snake embryos curl into a spiral, allowing their long bodies to develop inside an egg.

Caught right-handed: Mystery of coiling snake embryos explained

An international team led by Canadian researchers has found evidence explaining why snake embryos form a curious spiral. This ability to coil as embryos enables snakes to hatch with the longest bodies of all vertebrates.
