This freshwater pearl mussel Margaritifera margaritifera is probably much older than me. Although they can be more than 134 years old, their population in Estonia is going to be extinct due to their complicated reproduction system and the bad condition of the rivers they live in. In this year's Photo competition of the magazine 'Estonian Nature' this picture got a special prize as the best photo of an aquatic animal.
