The paper, by R.L. Cooper at University of Sheffield in Sheffield, UK, and colleagues was titled, "An ancient Turing-like patterning mechanism regulates skin denticle development in sharks." ...

Shark skin is made up of hundreds of millions of scales—called denticles—that are shaped like a three-toed dinosaur track. The curved bottom of the "foot" faces outward, while a cylindrical ...

sharks, rays, skates, and chimaeras are cartilaginous fish, meaning their skeletons are made of cartilage, not bone. Their skin is covered with denticles, tooth-like scales that differ from the ...

It's made up of thousands of dermal denticles, the toothlike structures ... forcing the water past and away from the shark's body, significantly reducing drag and even pulling sharks forward.

The skin of sharks and rays are covered in a layer of denticles, which are essentially microscopic teeth. Thorny skates get their namesake from their sickle-shaped barbs that are made from the same ...

One thing that ship hulls and medical tubing cannot yet do is to grow dermal denticles the way shark skin can. The shark is refreshing its skin surface continuously. It’s likely that a ...
