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.
– Blue glaucus can grow up to 1.2 inches (3 cm) long.
– Blue glaucuses eat large, venomous prey, such as the Portuguese man o’ war and the blue button jelly, and store their prey’s stinging cells in their bodies to later use against predators.
– Blue glaucuses can swallow air and hold it in their stomach in order to float on the water’s surface.
– A group of blue glaucuses floating together is called a “blue fleet.” These “blue fleets” often wash ashore and can sting people swimming in the water.
– Blue glaucuses lay eggs on their prey’s carcasses or other floating masses.
