2 Dollars Orange Darien Stubfoot Toad

Palau's wildlife conservation series, launched in the early 2000s, was one of the first Pacific island programs to systematically use numismatic issues to fund and publicize endangered species research. The Darien Stubfoot Toad (Atelopus spurrelli) is native to Colombia and Panama — not Palau — which reflects the broad conservation mandate rather than any geographic claim. The species had already experienced severe population collapses by 2011 due to chytridiomycosis, the fungal disease that has devastated amphibian populations across Central and South America since the 1980s.
