Rays, whether they are manta rays, sting rays, or mobulas, swim in a different way from any other swimming creature because they are shaped like pancakes with faces. What's weird is that parts of their faces are on top, and the rest is on the bottom. But you already knew that, and this video is from Ze Frank, so we also learn about their body teeth, their arrowhead with a stutter, their creepyholes, their waterfall of teeth, and their ampullae of lorenzini. You'll have to watch the video to find out what those are. Different kinds of rays have various weird ways of eating, and some even have superpowers like eletrocution or eating with their fins. He doesn't even get to the flying mobulas. This particular True Facts video is rather clean compared to others in the series, but it's still pretty funny in places. There's a 70-second ad at 5:05.
