what is shark skin like
Shark Skin-Like Surface Fights MRSA. Surfaces covered in a micropattern mimicking the ridges of shark skin could reduce the spread of drug-resistant Staphylococcus aureus and other superbugs in hospitals. With the rise of microbes that have evolved resistance to even the most powerful antibiotics, researchers are getting creative.
The skin of a shark is made of tiny denticles, which are made of the same enamel that teeth have, meaning they too can fossilize. Some more primitive sharks have spines in their fins that will fossilize. Finally, shark feces, or coprolites, are sometimes found preserved.
