- To celebrate the "United Nations Decade of Ocean Science for Sustainable Development", this Coin Series embarks on an undersea adventure that shows just how fascinating and colourful the underwater world can be.
With a mintage of 65,000, of the twelve innovative 3 Euro Coloured Coins in the Series, four will be issued each year over 3 years.
As improbable and magical as the sea creatures featured on the coins may seem, they really do exist.
Even though some of them live in the perpetual darkness of the deep seas, where no ray of sunlight penetrates, they all have extraordinary luminous qualities. They flash, sparkle and glow and change colour when necessary.
The same applies to the coins themselves, which glow when exposed to ultraviolet light in a way that is both exciting and piques our sense of scientific curiosity.
A dedicated ultraviolet torch will help the viewer to experience the charming creatures of Luminous Marine Life in full.
The Tenth Coin in the Series: The "DORODID NUDIBRANCH":
Description
A perfect example of how nature creates art without even trying, the doridid nudibranch makes a feather boa look dull by comparison. Admired for its eccentric shape and vibrant colours, which transform under ultraviolet light, the shell-less sea slug features on the eleventh coin in the Luminous Marine Life series.
The dazzling colouration of many types of nudibranch is believed to serve as a warning signal to predators, which is enhanced by their ability to glow, especially at night, in deep water or in caves and crevices. The human eye cannot perceive this biofluorescence, but many predatory fish can.
Nudibranchs are not typical hard-shelled molluscs that rely on a shell for protection. Instead, they use potent toxins that make any fish attempting to swallow a nudibranch quickly spit it out. Moreover, nudibranchs can even repurpose the defence mechanisms of the creatures they feed on, such as sea anemones. They harvest the highly venomous stinging cells from the polyps of these flower-like animals and store them for future use. When threatened, they unleash the ‘stolen’ stinging capsules to fend off their attacker.
Nudibranchs are ‘simultaneous hermaphrodites’, meaning that they are both male and female at the same time.
This is a significant advantage, as during mating, both partners can fertilise each other. Their egg masses –usually thousands of tiny eggs – resemble colourful flowers or garlands. From these eggs, larvae hatch and drift through the sea as part of the plankton for a short time. During this early stage of life, nudibranchs still have a microscopic shell. It is only when the larvae develop into small, bottom-dwelling snails that they lose their tiny shell entirely.
Coin motif:
All 12 of the magical sea creatures in the Luminous Marine Life series are shown in silhouette on the coin’s obverse.
Air bubbles up between them and a tail fin disappears beneath the waves to the right.
On the coin’s reverse, a wide band, reminiscent of an old-fashioned porthole frames an aquatic scene that, while apparently black and empty in normal light, is seen to feature several luminescent squid once the coin is illuminated with ultraviolet light. The squid appear in shimmering blue and purple tones, whereas the navigation element on the left appears green.
A collector coin that also makes for an exciting and educational gift for children, the Firefly Squid is aimed at vividly demonstrating the beauty and vitality of the underwater world along with the other coins in the Luminous Marine Life series.

The Coin:
The peripheral inscriptions are -"NACKTKIEMERSCHNECKE 2025".
The value side presents, in the style of a paper cut-out, all the sea creatures that appear in the 12-piece coin set "Shining Sea Worlds". Air Bubbles can be seen between them, and to the right of them is a tall fin diving into waves.
The whole thing is framed by a historic-looking porthole decorated with a starfish and a shell.
If the coin is illuminated by a UV flashlight, the fish begins to fluoresce green and a little blue.
The wide band, reminiscent of an old-fashioned porthole frames an aquatic scene that features a "The Doridid Nudibranch" in the centre.
Together with the other "Glowing Sea Worlds" coins it aims to vividly demonstrate the beauty and vitality of the underwater world.
To ensure that the marine habitat remains as diverse as it is on the colourful coins, we have to protect it - from ourselves.
On the Obverse of the 3 Euro Base Metal Coin, all 12 of the magical sea creatures in the "Luminous Marine Life Coin Series" are shown in silhouette.

Co-developed with marine researchers, this Collector album not only stores all 12 coins in the Luminous Marine Life series but is also crammed with fascinating information about the 12 sea creatures that feature on them.
The album explains in detail how they live in and illuminate their aquatic environment and how vital that environment is for our planet as a whole, the threats it faces from humans and shows what can be done about it. It does so in a style that is understandable for youngsters yet entertaining for adults, making it a source of fun for coin collectors of all ages. You will learn, for example, about the ingenious deep-sea angler fish, which uses its very own illuminated fishing rod to lure its unsuspecting prey when hunting.
The album concludes with a quiz where you can have fun testing your newly acquired knowledge of marine biology.
It is only available in German language.
In addition to a dedicated Collector album, Luminous Marine Life also comes with its own special tool for enhancing the visual experience of the 12 coins in the series:
Through UV light, the torch maximises the experience by making the sea creatures on the coins really shine and glow. By shining the torchlight on the coins, the sea creature can be seen to change colour.
One can also use the torch to discover whether 2 of the 12 marine animals on the coins are nothing but dark or are harbouring a bright secret. And the fun does not stop with the coins themselves – illustrations and information are also hidden here and there throughout the album. By examining the pages with the torch, with a bit of luck one may discover them.
UV light is an abbreviation for ultraviolet light, which is also as known ‘black light (UV-A)’. Important instructions on how to use the lamp safely can be found on the back of the torch packaging.
