"It would be like trying to understand what was reported in a newspaper by taking scissors to a rolled-up copy. "Intestines are so complex, with so many overlapping layers, that dissection destroys the context and connectivity of the tissue,” co-author Adam Summers, a professor based at UW Friday Harbor Labs, explained in the release. This meant researchers didn’t have to dissect a shark and disturb the organs involved. ![]() This process involved taking a series of X-rays from different angles and then combining those flat images to produce a 3D one. Researchers took CT scans of around three dozen shark species from specimens preserved at the Natural History Museum of Los Angeles. "We developed a new method to digitally scan these tissues and now can look at the soft tissues in such great detail without having to slice into them." "It's high time that some modern technology was used to look at these really amazing spiral intestines of sharks," Samantha Leigh, assistant professor at California State University and lead author of the study, said in a press release. ![]() 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.īut new 3D imaging may have unravelled some of those digestive mysteries by creating a better picture of what a shark’s intestines look like.Īccording 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.
