Lisa Ray Instagram – Posted @withregram • @atmos Have you ever seen a Spanish dancer swim? 💙 Hexabranchus sanguineus is a nudibranch—a very large and colorful sea slug—that feeds on marine sponges and toxic jellyfish, assimilating their poisons for their own chemical defence. Their bright coloration serves as a warning to potential predators that they don’t taste good and can make predators sick. These propelling moves are thought to be unique to the Spanish dancer as the only Nudibranch that can swim as well as crawl along the sea floor. Video by @fathomlesslife
