The Glaucus Atlanticus Sea Slug is as unusual as its appearance suggests — this thing is honestly pretty weird, but we can forgive it since it is so breath-taking. These creatures are three centimeters long and predominantly colored with silver and blue tints. They are found in tropical waters, specifically those off of the coast of Africa and Australia. Though they exist predominantly in these locations, they can also be found off of European coasts. The Glaucus Atlanticus Sea Slug floats on top of the water by using it’s gas filled sac. Surprisingly, these tiny slugs actually feed on large, dangerous, poisonous animals; namely the Portuguese Man O’ War. Yeah, those are the things that you try to avoid at all costs whenever you go snorkeling in the ocean, because their stings hurt like no other. According to marine biologists, the sea slug can and usually does consume the entire Man o War organism and absorbs the toxins from the creature it just preyed upon, and then saves that poison as a self-defense mechanism. Pretty amazing given the size of the Sea Slug.
