Ze Frank takes on a big subject for his latest True Facts video: crabs. Here we learn more than we ever knew about the Christmas Island crabs, which fling their offspring into the water and scurry away. Then he covers hermit crabs that grow up to be giant coconut crabs. The sponge crab uses living sponges for hats, while other decorator crabs use all manner of marine life as accessories and weapons. There are so many crab species that there's something truly weird about each of them. But they all molt as they grow, and some can be partially eaten and just regenerate. That won't make you feel any less guilty about eating crab legs, because those crabs are harvested whole. Rather, you should tell yourself about all the crabs that eat other crabs. This video is a bit long, but the whole thing is fascinating. There's a skippable ad from 2:30 to 3:30, which might save you time. As always, this video contains PG language and innuendos.
