Journey of Turtle from East Java to Australia Reveals Oceanic Superhighway Mistery

Meet Ana, a female green turtle. Her extraordinary journey from Indonesia into Australian waters is helping conservationists to track the migratory route of this species to the Kimberley-Pilbara coast, one of the few relatively pristine coastal areas left on Earth.

Ana was tagged in Indonesia in November 2008 as part of a turtle tracking project by WWF and Udayana University in Bali, Indonesia, and has slowly made her way from a nesting beach in East Java, across the Indian Ocean, and is on track for the beaches of the Kimberley in Western Australia.

The journey, monitored online by WWF, demonstrates the strong biological ties between Indonesia and the reefs on the west Australian coast. Ana has revealed an ‘oceanic superhighway’ that helps us better understand how marine turtles navigate around the world’s oceans as well as highlighting the strong ecological and evolutionary connections between Indonesia and Australia’s Kimberley-Pilbara coast.

Gilly Llewellyn, WWF Ocean’s Program Leader, said, “This new finding throws the spotlight on the true natural values of the magnificent Kimberley marine ecosystem and its link to the Coral Triangle to the north, the world’s epicentre of marine biodiversity and the cross-roads of migration routes and breeding grounds for whales, turtles, dolphins and other precious marine species.”

The Coral Triangle spans Indonesia, Malaysia, Philippines, Solomon Islands and Timor Leste, and contains critical habitat for six of the world’s seven species of marine turtles, including green, hawksbill, olive ridley, leatherback, loggerhead and flatback turtles.

All of these species are threatened with extinction as a result of pollution, long-line and trawl fishing that results in the accidental catch of marine turtles, and an illegal trade in turtle eggs, meat, shells and skin.

“Ana’s journey has shown us areas where we need to focus our efforts. We need to tap into the secret lives of species such as turtles, so we can design networks of marine protected areas that conserve the full range of plant and animal life, and ensure their longevity for years to come.” [story from WWF release, photo from iStockPhoto, graphic of Ana’s track from]


Perjalanan mengesankan seekor penyu hijau dari Indonesia menuju perairan Australia membantu pecinta lingkungan melacak jalur migrasi spesies ini. Ana, penyu hijau betina dewasa, yang diberi penjejak satelit pada 26 November 2008 memulai perjalanan menyusuri perairan dangkal Samudra Indonesia dari pantai petelurannya di Sukamade menuju Bali, Lombok, dan Sumbawa, dan akhirnya berbelok ke selatan menuju pantai Kimberley di Australia bagian barat. Perjalanan Ana yang diawasi melalui satelit oleh WWF memberikan gambaran tentang keterikatan lingkungan yang kuat antara perairan Indonesia dan perairan Australia Barat di masa lalu.
