Check out this submarine that looks like a dolphin. It’s called the Innespace Seabreacher, a two-seater submersible that looks and moves like a dolphin. Interestingly, the Seabreacher uses the same canopy as an F-22 fighter jet to insure that the inside stays nice and dry with a watertight seal. The vehicle seems a lot like a jet fighter for the water when you see it in motion.
Since it’s made to mimic a dolphins movement, it uses the downward lift of the wings to jump out of the water, and even do barrel rolls. I suppose it’s as close as humans can get to actually being a dolphin. You have to wonder what the dolphins think about all this. Check out a video below.
