The stamp illustrates the wels catfish captured in their natural habitat by the passionate diver photographer Cristian Mitrofan. The charm of the image is amplified by the presence of plants, visible only under the water mirror. Water thus presents itself as an environment of symbiosis between underwater fauna and flora. The wels catfish (Silurus glanis) is a species of freshwater fish from the Siluridae family, spread in Europe and Asia Minor, where it lives mainly in running waters, but also in clean stagnant waters with a sandy bottom.
Underwater flora brings together aquatic plants that live and grow under water.
