Few people have gotten close enough to a shark to pet it. If you could run your hand from a shark’s head to its tail—not that you should—it would feel smooth, almost like suede. Reverse direction and it’s rough like sandpaper. Viewed under a micros...
One of the key evolutionary attributes sharks have is their peculiar skin. Although sharkskin looks smooth to the naked eye, it is in fact rough upon contact. If you examine sharkskin under a microscope, you can see it is made up of many small, sharp tooth-like scales which are called ...
When viewed under a microscope, these tiny scales resemble spoilers on fast cars. One of their functions is to reduce water resistance and aid the smooth movement of the shark through the water. Some companies are even trying to emulate shark scales in an effort to create swimming and diving...
Like large boats, whales and other marine animals have “crusty” skin due to the build-up of algae. But sharks’ skin stays remarkably clear. The question was why. “I wonder what their skin is made of, ” he thought. Viewed under a microscope, the shark’s skin had a pattern of...
The question was why. "I wonder what their skin is made of" he thought. Viewed under a microscope, the shark's skin had a pattern of dips and ridges. He included the shark skin pattern on his test panels and that cut the build-up of green algae by 85percent. Brennan later discovered...
"All these slights to their ability to function at the level they do now add up," said Cape Eleuthera's Talwar, who had no role in the research. "Then, [degraded skin] is a much bigger issue." Original image has been replaced.Credit: Mashable ...
(EDS) in the scanning electron microscope to show that the enameloid is chemically homogeneous. Based on field-emission scanning electron microscopy, as well as Raman microspectroscopic imaging, we then demonstrate and quantify an unusual graded microarchitecture of the enameloid. Finally, we show ...
Ventral skin patches (,0.25 cm2) were excised from the centre of the maximum ventral photophore density area of specimens from 37 distinct species (Supplementary Data 1) and photographed under a binocular microscope (Leica MZ6, Wetzlar, Germany). Pictures were analysed in Image J v. 1.46 ...

By copying the microscopic structure of shark skin onto metal, the research team creates a super-hydrophilic, or water-wicking, material. This property reduces drag and could be used to create submersible craft that travel farther underwater using less power. ...
