| 正面描述 | The violet-hued niobium centre features a large nautilus shell rendered in bold relief, its characteristic logarithmic spiral dominating the inner field, with a hummingbird in flight depicted above and a shark in the lower field — natural forms emblematic of bionics. The surrounding silver ring bears relief imagery of a lotus flower to the left and an aircraft silhouette in the upper field, illustrating the theme of human technology inspired by nature. The denomination '25 EURO' and date '2012' appear to the right within the niobium core. The legend 'REPUBLIK ÖSTERREICH' is inscribed along the lower arc of the silver ring in raised Latin characters. |

| 背面描述 | The violet niobium centre depicts a large dragonfly wing rendered in exceptional detail, its intricate venation pattern filling the inner field and illustrating the bionics theme of engineering solutions derived from natural structures. To the left of the wing, a textured globular form — evocative of a compound eye or seed head — is shown in high relief. The surrounding silver ring displays an array of bionic motifs in the field, including a honeycomb lattice structure to the upper left and a layered architectural or composite material pattern to the right, underscoring the interdisciplinary nature of the subject. The legend 'BIONIK' is inscribed along the upper arc of the silver ring in spaced raised Latin capitals. |
