2019 - Austria - 3€ BU "Crayfish"

3 euro coin dedicated to the crayfish, Brilliant Uncirculated. GLOW IN THE DARK! Crayfish, freshwater relatives of the lobster, live only in unpolluted streams, river and lakes as they cannot tolerate contaminated water sources. For this reason, although once abundant throughout the continent, the European crayfish, also known as the noble crayfish, has seen its numbers dwindle.
