God designed sharks to slice through the water with minimal resistance. Their skin is covered with tiny rectangular scales that have small spines poking from the top. This makes their skin feel rough. In addition to helping sharks move easily in the water, this design also keeps barnacles and other organisms from attaching and growing on their skin.
Researchers have been studying the properties of the shark’s well-designed skin in order to help boaters keep their boats clean. Boats usually have smooth surfaces, but redesigning the surface to match the shark’s skin may help boats move better through the water and keep their hulls free of barnacles. Shark skin has even inspired the design of swimsuits and wet suits. Copying the Master Designer leads to superior designs!
