New 3D images of shark intestines show they work like Tesla valves

TORONTO Despite sharks being frequently cast as the ‘scary creature with large teeth’ in our collective imagination, not a lot is known about what sharks actually eat and how they can go so long between meals. But new 3D imaging may have unravelled some of those digestive mysteries by creating a better picture of what a shark’s intestines look like. According to a new study published in the journal Proceedings of the Royal Society B, researchers have made images using CT scans that allow a closer look at the animal’s spiral intestines, which may allow it to digest food slowly.

Sharks spiral-shaped intestines resemble a Nikola Tesla invention

Samantha Leigh/California State Sharks have spiral-shaped intestines that work in a similar way to an unusual valve designed by Nikola Tesla. Studying their anatomy could help improve industrial fluid-pump technology. Most animals have tubular intestines that use muscle contractions to push food along like squeezing a tube of toothpaste. But sharks slowly channel their meals through spirals without needing muscles to push the food. Their intestines are also shaped in a way that only allows food to flow one way – like a performance-enhanced Tesla valve, says Samantha Leigh at California State University Dominguez Hills. “Sharks have all these different little tweaks to the Tesla valve design that could be making them more efficient,” she says.
