I’ve said it before and I’ll say it again: Nature is awesome. To be completely honest, it’s sometimes frightening-awesome, if that makes any sense. You’ll see what I’m talking about once you take a look at the video below. The clip shows one of the weirdest-looking creatures I’ve ever seen swimming in a tank. Apparently, it’s a bristle worm, which, as it turns out, are everywhere in the ocean. Bristle worms truly are fascinating creatures. They are quite the fighters also, considering they have survived five mass extinctions. Also, they can grow up to impressive lengths. The one in this video is more than 40 inches long.
