Rays: Floppy Sombreros of the Sea

Rays, whether they are manta rays, sting rays, or mobulas, swim in a different way from any other swimming creature. 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. 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.
