Shark Intestines
You may be wondering why shark intestines are one of those scientific mysteries that made it on this list. Well, it was recently discovered that shark intestines are closely related to the function and design of Tesla valves. Yes, you read that correctly. Since every species of animal has intestines that come in all shapes and sizes, each differs vastly from the next. But the sharks are closely related to Tesla. According to Smithsonian Magazine, “shark intestines slowly move digested meals through spring-shaped spirals or nested funnels, depending on the species, to eke out every last calorie and eliminate the rest.”

This is eerily similar to Tesla. They also mentioned that “the twists, turns, and funnels ease fluids forward, which could be an energy-saving form of digestion.” This means that could translate to energy-saving efficiency with Tesla. Animal physiologist Samantha Leigh, from California State University, said “sharks have all these different little tweaks to the Tesla valve design that could be making them more efficient.” It looks like we can now use the insides of animals to try and create inventions by replicating their structure and shape. There’s a reason their intestines are shaped like that (Smithsonian Mag).
