The inclusion of animals on Philippine currency represents a deliberate shift in national symbolism, moving from historical figures to ecological ambassadors. This transition, formalized in the 2025 First Philippine Polymer Banknote Series, reflects a strategic alignment with biodiversity conservation goals and cultural identity. Below, we analyze the multifaceted requirements for an animal to be featured on Philippine money, drawing from legislative frameworks, conservation priorities, and socio-political considerations.
Endemic Status as a Foundational Criterion
A primary requirement for an animal’s inclusion on Philippine currency is its status as an endemic species—one found exclusively within the archipelago. The Bangko Sentral ng Pilipinas (BSP) explicitly prioritizes species that embody the Philippines’ unique biogeographical identity14. For instance, the Philippine eagle (Pithecophaga jefferyi), featured on the 1,000-piso note, is endemic to Mindanao and symbolizes national strength due to its status as a critically endangered apex predator14. Similarly, the Visayan spotted deer (Rusa alfredi), depicted on the 500-piso bill, is confined to the fragmented rainforests of Panay and Negros, making it a flagship species for regional conservation45.
This emphasis on endemism serves dual purposes: it fosters national pride by showcasing species absent elsewhere and underscores the urgency of protecting habitats under threat from deforestation and urbanization14.
Conservation Status: Threatened Species as Ecological Ambassadors
Animals featured on Philippine banknotes must occupy a threatened conservation category as defined by the International Union for Conservation of Nature (IUCN). The BSP’s selection process aligns with the Department of Environment and Natural Resources (DENR) Biodiversity Management Bureau’s mandate to prioritize critically endangered species13. For example:
- The Palawan peacock-pheasant (Polyplectron napoleonis), on the 100-piso note, is classified as vulnerable due to habitat loss from mining and illegal logging4.
- The Visayan leopard cat (Prionailurus bengalensis rabori), featured on the 50-piso polymer note, is a vulnerable subspecies surviving only in Panay, Negros, and Cebu4.
By highlighting these species, the BSP amplifies awareness of their plight, leveraging daily currency interactions to remind citizens of their shared responsibility toward conservation14. This approach is reinforced by Republic Act No. 9147 (Wildlife Resources Conservation and Protection Act), which criminalizes habitat destruction and illegal trade of endangered species3.
Cultural and Symbolic Resonance
Beyond ecological significance, animals must embody cultural or symbolic values that resonate with Filipino identity. The sampaguita (Jasminum sambac), paired with the Philippine eagle on the 1,000-piso note, represents purity and resilience—traits historically associated with national heroes14. Similarly, the maliputo fish (Caranx ignobilis), once featured on older 50-piso bills, holds cultural significance in Batangas cuisine and folklore, even as its near-extinction in Taal Lake spurred conservation legislation24.
This symbolic alignment extends to indigenous communities. The T’nalak weave design on the 1,000-piso note and the embroidery patterns from Batangas on the 50-piso bill integrate traditional artistry with wildlife imagery, creating a narrative of cultural continuity intertwined with ecological stewardship45.
Policy Alignment and Institutional Endorsement
Inclusion on currency requires formal endorsement from governmental and environmental institutions. The DENR’s Biodiversity Management Bureau collaborates with the BSP to vet species based on their ecological and cultural merits14. For instance, the selection of the Visayan spotted deer followed consultations with conservation NGOs like Haribon Foundation and Wildlife Matters, ensuring the species’ representation aligns with ongoing habitat restoration projects in the Visayas15.
Additionally, the BSP’s design choices reflect broader policy shifts. The displacement of historical figures like Corazon Aquino and Benigno “Ninoy” Aquino Jr. by the Visayan spotted deer on the 500-piso bill signals a prioritization of environmental advocacy over political narratives5. This transition is codified in the BSP’s cyclical design review process, which mandates thematic updates every decade to address contemporary national priorities14.
Economic and Ecological Interdependence
Animals featured on currency must also represent economic-ecological interdependencies. The blue-naped parrot (Tanygnathus lucionensis) on the 500-piso bill, for instance, is not only critically endangered but also a key species for ecotourism in Puerto Princesa Subterranean River National Park45. Similarly, the whale shark (Rhincodon typus) on the 100-piso note underscores the economic value of marine biodiversity, as Donsol’s whale shark tourism generates millions annually for local communities4.
This criterion ensures that currency designs reinforce the message that biodiversity conservation is not merely an environmental concern but a socioeconomic imperative. By linking species survival to livelihoods, the BSP incentivizes public support for conservation funding in congressional appropriations13.
Legislative and Enforcement Frameworks
The legal protection status of a species plays a critical role in its eligibility for currency inclusion. The Revised Animal Welfare Act (RA 10631) mandates stricter penalties for cruelty toward endangered species, creating a legislative backdrop that validates their symbolic prominence3. For example, the inclusion of the Philippine eagle—a species protected under RA 9147—on the highest-denomination banknote underscores the legal gravity of its conservation14.
Moreover, the BSP’s partnership with law enforcement agencies, as outlined in RA 10631, ensures that species featured on currency benefit from enhanced protection mechanisms, including deputized animal welfare officers and community-led anti-poaching initiatives34.
Public Engagement and Educational Value
Finally, animals must possess educational value capable of driving public engagement. The BSP prioritizes species with distinct morphological or behavioral traits that captivate public interest. The Philippine tarsier (Carlito syrichta), though not currently featured, has been flagged for future series due to its unique large-eyed appearance and role in promoting Bohol’s tourism24. Similarly, the iridescent plumage of the Palawan peacock-pheasant serves as a visual tool to educate citizens about avian diversity4.
This educational mandate is advanced through collaborations with NGOs and academic institutions. For instance, the BSP’s partnership with the University of the Philippines’ Institute of Biology ensures scientific accuracy in species depiction, transforming banknotes into portable educational materials14.
Conclusion: A Holistic Approach to Currency Symbolism
The inclusion of animals on Philippine currency is governed by a rigorous, interdisciplinary framework that balances ecological urgency, cultural relevance, and policy alignment. Species must be endemic, threatened, symbolically resonant, and legally protected, while their representation must advance public awareness and economic sustainability. As the Philippines navigates the dual challenges of biodiversity loss and climate change, its currency serves as both a mirror of national identity and a catalyst for conservation action. Future iterations may expand to include marine species like the Tubbataha Reef’s hawksbill turtle or the Apo Island’s giant clams, further entrenching the peso’s role as a testament to the archipelago’s natural wealth.
