Raincoats, plastic bottles, styrofoam, windshield wiper motors and a love for the sea; that’s what marine biologist and self-taught roboticist Masamichi Hayashi used to make these realistic aquatic robots. Among Hayashi’s creations are a porpoise, great white shark, green turtle, manta ray, killer whale and hammerhead shark. Back in 2009 they were featured on Japanese TV, Hayashi explained how they are used to teach kids about marine animal behavior and locomotion.

The 5 ft long coelacanth robot below weighs 105 lbs and cost 2 million yen ($22,000) to make.
