In a statement, Leigh says these insights into the design of sharks’ digestive tracts could provide engineers with inspiration in applications, including wastewater treatment and filters designed to remove plastic pollution from water. Sharks 3D (2004) on IMDb: Movies, TV, Celebs, and more.
“My hope is to figure out what these particular morphologies are good at moving along, what they’re good at filtering out,” Leigh tells the Times.

Sharks (in 3D): Directed by Benjamin Eicher, Timo Joh. Great white shark (Carcharodon carcharias) Great white shark. Samantha Leigh / California State University, Dominguez Hills A shark’s spiral intestine (below) has a similar structure. And, similar to Tesla’s one-way valve, the twisted architecture promotes a one-way flow through the digestive tract and potentially reduces the energy the sharks expend pushing food in the right direction with muscular contractions.Ī Tesla valve (above) creates one-way flow without backflow or moving parts.

These digital 3-D models, as well as experiments in which the researchers pumped fluid through the shark intestines, revealed the spiral shape slows down the passage of food, which may help sharks extract every last calorie from their food.

Then, the team created 3-D models of the shark intestines using computerized tomography (CT), which takes a large number of cross-sectional X-ray images and combines them to make a digital model. To preserve these shark guts in a life-like arrangement, the researchers filled the organs with fluid and freeze dried them.

As Greenwood writes in the Times, the sharks in the study have four different types of spiral intestines: “a basic spiral, a nested series of funnels pointing one way, a nested series of funnels pointing the other way, and what’s called a scroll intestine, where layered sheaths nestle within each other.” To get around this problem, Leigh and her co-authors removed the entire digestive tracts from 32 dead sharks (all donated or taken from museum collections) from 22 different families. It wasn’t a mystery that sharks had corkscrewed digestive tracts, but when researchers dissected them to study, the process often damaged the organs’ delicate structure, obscuring how they functioned internally.
