Croatian scientists are undertaking a last-ditch effort to save the noble pen shell from extinction. The species, now critically endangered, is the focus of a unique conservation project based in Pula. Researchers are working within a specialized laboratory to develop methods for reviving the dwindling population. The initiative reflects the severity of the species’ decline and the urgency of the situation. Details of the specific techniques being employed remain limited, but the project signifies a commitment to biodiversity preservation. The effort aims to prevent the complete disappearance of the noble pen shell from Croatian waters and potentially beyond.
