Green Sea Turtle
Also known as: Pawikan (Filipino) · Chelonia mydas (scientific name) · Green turtle · Honu (Pacific-wide name, used in some PH references)
Definition
The green sea turtle (Chelonia mydas), called pawikan in much of the Philippines, is a large marine turtle named for the greenish fat beneath its shell rather than its scutes, and the only species in its genus. Grazing seagrass meadows and nesting on sandy beaches across the Philippine archipelago — including the globally significant rookeries of the Turtle Islands off Tawi-Tawi — it is classified as Endangered, and its story in the country spans subsistence hunting traditions, celebrated conservation programs, and community-guarded hatchery releases.

Examples and Analogies
- The seagrass lawnmower: By cropping seagrass beds the way large herbivores mow grasslands, the green turtle keeps meadows productive — remove the mower and the lawn, along with the fish nursery it shelters, degrades.
- Natal homing navigator: Like a retiree returning to a hometown street, an adult female swims hundreds or thousands of kilometers to lay eggs on the very beach where she hatched.
Usage Scenarios
1. Nesting-Beach Protection
Coastal communities and protected areas in Palawan, Tawi-Tawi, and elsewhere patrol beaches, relocate doomed nests, and release hatchlings during the nesting season.
2. Marine Ecotourism
Snorkel and dive sites from Apo Reef to marine sanctuaries market turtle encounters that fund local conservation fees.
3. Seagrass Ecosystem Monitoring
Turtle presence and grazing patterns serve as indicators of seagrass health in coastal resource management.
Strategies
- Guard nesting beaches with community wardens who offset egg-poaching incentives with livelihood support
- Reduce fisheries bycatch with turtle excluder devices and modified hooks in waters with high turtle traffic
- Protect seagrass beds and avoid coastal lighting that disorients hatchlings heading to sea
Security and Safety Measures
- The species is protected by Philippine wildlife law and international treaties, penalizing hunting, egg collection, and trade in turtle products
- Hatchery protocols — shaded relocation, clutch-depth mimicry, night releases — keep rescued nests viable
- Interaction guidelines for divers and tour operators prohibit touching, riding, or chasing turtles to reduce stress and injury
Historical Context
Green turtles nested on Philippine beaches in numbers that sustained centuries of traditional egg and meat harvest, particularly around the Sulu Sea. Twentieth-century commercialization drove steep declines, prompting protection programs that became pillars of Philippine marine conservation: the Turtle Islands was established as a protected area jointly managed with Malaysia, hatcheries multiplied along nesting coasts, and satellite tracking revealed the vast migrations of Philippine-tagged adults across Southeast Asia. Today community-led releases of hatchlings are among the country’s most visible — and photogenic — conservation rituals.
Challenges and Controversies
Poaching and Illegal Trade
Despite protection, eggs and meat move through black markets, and the discovery of large shipments of seized turtle products periodically exposes the trade’s scale.
Coastal Development
Beach resorts, seawalls, and artificial light degrade nesting habitat exactly where tourism values the turtles most, forcing hard zoning conversations.
