Results: The blue dragon

This up-to-3-centimeter-long animal, uses a form of camouflage called countershading that protects it from both flying and swimming predators while it floats. The underside of the blue glaucus, which faces upward, is blue, helping it blend into the water's surface when seen from above, while its back, which faces downward, is a more grayish color, helping it blend into the ocean when seen from below. Can you mention any other creature that uses countershading camo?

It feeds on hydrozoans (a group of animals in the same phylum as jellyfish), especially the highly poisonous Portuguese Man-O'-War. Although a sting by a Portuguese Man-O'-War is very painful to a human, the blue glaucus, can swallow its prey's stinging cells without hurting itself. It may keep itself safe from the poison by releasing protective mucus and by hard barrier-like discs inside its skin. Do you know any other creatures that can eat poisonous preys without getting any damage?

The blue dragon stores the swallowed poison inside the up to 84 finger-like structures sticking out of its body, and then uses this poison to defend itself against other predators. Have you ever been hurt by a poisonous creature?
