    This Wild and Wonderful World of Ours! 🐌

    Introducing..........the Blue Glaucus......

    Also known as blue dragons, blue angels and sea swallows.

    Despite its impressive arsenal of defense tactics, the blue glaucus rarely reaches more than 3 centimeters long (about an 1.2 inches).

    An air bubble stored in its stomach keeps the slug afloat. The creature often floats on its backside, showing its brightly colored underbelly to airborne predators. The bright blue color acts as camouflage against the backdrop of ocean waves while the animal’s grayish backside blends with the bright sea surface, concealing it from predators below.

    Like other sea slug species, the blue gaucus isn't venomous by itself. When feeding on its preferred prey, Portuguese man o' wars, the blue gaucus stores the stinging nematocysts created by the prey’s notoriously long, venomous tentacles β€” these tentacles may average up to 30 feet long! The stinging cells are stored and concentrated for the future, so when the blue dragon is threatened or touched, it can release these stinging cells to deliver a far more potent sting than the Portuguese man o' war can alone.

    The blue gaucus, like all slugs, is hermaphroditic β€” each individual produces both eggs and sperm. An individual cannot fertilize its own eggs, however, and pairs still must mate. Long, spiral-shaped eggs are produced by both male and female, and often float freely in the water or stick to nearby surfaces. Blue glaucuses lay eggs on their prey’s carcasses or other floating masses.

    A group of blue glaucuses floating together is called a β€œblue fleet.” These β€œblue fleets” often wash ashore and can sting people swimming in the water.

    They prefer the warmer water of the South Africa, Mozambique, Pacific and Indian Oceans, Australia and earlier this year a fleet landed on the beaches of Florida.
