Mako sharks are the fastest sharks in the ocean - thankfully they have all sorts of equipment to help them vent all that speed. I hope that kind of looks like a treadmill.
The more common Mako is the shortfin Mako (Isurus oxyrinchus). These beautiful and incredible sharks are hunted for sport by people with brains that have some sort of short-wiring. They are now considered endangered on the IUCN red list.
