Description

To celebrate the United Nations Decade of Ocean Science for Sustainable Development, the Austria Mint embarked on an undersea adventure showcasing the fascinating and colorful underwater world. With a mintage of 65,000, the series featured 12 innovative 3 euro colored coins, four of which were issued each year over three years. These coins not only captivated with their design but also featured special lighting effects.

The sea creatures depicted on the coins, despite seeming improbable and magical, truly existed. Many lived in the deep seas' perpetual darkness, where sunlight never reached, yet they possessed extraordinary luminous qualities—flashing, sparkling, glowing, and changing color as needed.

Similarly, the coins themselves glowed under ultraviolet light, sparking excitement and scientific curiosity. A dedicated ultraviolet torch allowed collectors to experience the enchanting creatures of Luminous Marine Life in their full, radiant glory.

Depicts a wide band reminiscent of an old-fashioned porthole, that frames an aquatic scene and features a mauve stinger in the center. An island with palm trees can be seen above the surface of the water. When the coin is illuminated with ultraviolet light, the jellyfish glows and changes colour, so that the light brown of its bell turns blue or red, as does the pinkish purple of its tentacles and oral arms.

The mauve stinger (Pelagia noctiluca) is a delicate jellyfish known for its bioluminescent abilities. This transparent species glides gracefully through the water and can be found worldwide in tropical and warm temperate seas. Its entire body can emit a glow, and when touched, its bell and tentacles produce light lasting several minutes, triggered by an enzyme activating a luminescent molecule. The jellyfish's mucous coating also glows and can transfer its glow to other objects it contacts.

Both its tentacles and bell are covered in stinging cells, making encounters painful but generally not dangerous. Large swarms of mauve stingers can affect local economies by deterring tourists and clogging fishers' nets, sometimes even wiping out entire fish farms.
