They also have quite a sting that is able to kill other sea creatures.
We've read about mythical dragons and seen their imagined manifestations in movies. But what if we told you that you could see a version of these in real life? Be not afraid, they don't breathe fire. Not very long ago, some swimmers along an Australian coast saw these very brightly-colored sea creatures with dragon-like features with wings and a tail. Take a look at this video that was posted by one of them.
The creatures look like miniature dragons and no wonder they've been named after their mythical cousins. The blue dragons, scientifically known as Glaucus atlanticus, are an extremely bright blue with color patterns that can inspire a thousand artists. They spend most of their lives floating upside down in warm ocean currents, according to The Dodo. These are tiny sea slugs and are not all that harmless despite being little. They will grow to just about an inch long but have a powerful venom that can kill other sea creatures if they get too close. Their venom is in their wing-like appendages. Can these creatures harm humans?
Their sting may not kill but it does leave quite a sting and it's better you just look at them rather than pick them up. Take the word of Kylie Pitt, a marine invertebrates expert from Griffith University, Australia reports Gold Coast Bulletin. “I have handled them before and wasn’t stung, but I would not recommend anyone pick them up because they can have a painful sting. They are really weird...they float upside down and move around using the water’s surface tension.” She added these marine creature sheds its shell after larval stage. They come from the same family of underwater animals as cuttlefishes, squids, and octopuses, also known as molluscs.
Mollusks are any soft-bodied invertebrate of the phylum Mollusca, usually wholly or partly enclosed in a calcium carbonate shell secreted by a soft mantle covering the body. These creatures are actually very difficult to spot and are rarely seen by humans but we guess some people at a beach in the Queensland shore where they were found just got a bit lucky. According to Oceana, these sea creatures can be found in various oceans. "Also known as the blue dragon, sea swallow or blue angel, the blue glaucus is a species of brightly colored sea slug (nudibranch), and can be found throughout the Atlantic, Pacific and Indian Oceans in temperate and tropical waters. Like most nudibranchs, this species incorporates toxic chemicals or stinging cells from its prey into its own skin."
The foundation added, "This ability provides the blue glaucus with a defense mechanism against predation. Despite its impressive arsenal of defense tactics, the blue glaucus rarely reaches more than 3 centimeters long. And, unlike most benthic nudibranchs, this species lives throughout the entire water column. An air bubble stored in its stomach keeps the nudibranch afloat."
