---

Deep beneath the ocean waves lies a world of vibrant color and unexpected beauty. This 2025 cupro-nickel coin from Austria highlights one of the sea's most intriguing inhabitants, the doridid nudibranch, commonly known as a sea slug. Issued with a face value of 3 Euro, this piece is part of the captivating Luminous Marine Life series, which honors the United Nations Decade of Ocean Science for Sustainable Development. One side of the coin presents a detailed underwater scene, framing the sea slug inside a circular border reminiscent of a submarine porthole. In the background, a delicate coral reef and tiny swimming fish complete the aquatic landscape. The other side showcases a collective tribute to marine diversity, displaying the silhouettes of 12 different sea creatures alongside rising air bubbles and a tail fin slipping out of view. Struck in brilliant uncirculated quality by the Austrian Mint, this coin has a limited mintage of 65,000 pieces. It serves as a striking reminder of the delicate ecosystems thriving in our oceans and the ongoing global efforts to understand and protect them.
