The obverse of the coin is dominated by a cross section of the complex nautilus shell, often used as a model for leading edge modern design buildings. Above the nautilus an eagle flies – symbolizing the inspiration for an aircraft. The aircraft also has a special finish on the outer shell, which was based on sharkskin, that reduces friction and thereby allowing the aircraft to fly more efficiently. The lotus flower shown in the left centre of the silver ring gave rise to repellents. Also on the obverse of the coin and located in the silver ring is the country of issue “REPUBLIK ÖSTERREICH” and the year of issue 2012. The face value of the coin, 25 euros, is located in the right quadrant of the pure niobium design field. The reverse side of the coin shows an interior view of the Munich Olympic stadium, the roof of which was designed based on findings in the bionic world based on radiolarian shells. A highly magnified radiolarian shell is shown in the foreground.

The Austrian Mint has issued the tenth coin in the stunning and popular silver niobium bimetallic series, with this 2012 release dedicated to Bionics. Bionics is the complex interdisciplinary field in which biological systems and evolution are applied in solving engineering problems and developing modern technology.
