5 Rupees Dermochelys Coriacea

The Dermochelys coriacea — the leatherback sea turtle — holds a specific ecological significance to the Seychelles: the islands host some of the Indian Ocean's last viable nesting populations, with Silhouette Island documented as a critical nesting site. Seychelles has issued wildlife-themed coinage intermittently since the 1970s, often timed to coincide with conservation legislation or international environmental agreements rather than purely numismatic demand.
