Loggerhead turtles current-riding 20,000km round-trip

A marine biologist has helped fill in the so-called lost years of Australia’s loggerhead turtles by discovering they are using ocean currents to undertake a 20,000-kilometre, round trip across the Pacific Ocean.

Dr Michelle Boyle, of the School of Marine and Tropical Ecology at James Cook University, Queensland, and colleagues used genetic testing to track the migratory behaviour of the Australian-born loggerhead turtle (Caretta caretta), which hatches in rookeries on the Queensland coast.

Boyle says it appears the endangered turtles use the ocean currents that make up the South Pacific gyre to travel across the southern Pacific Ocean to the waters off Peru and Chile.

In scenes reminiscent of the animated movie Finding Nemo, they then pick up the East Australian Current (EAC), which they “ride” down the coast of eastern Australia.
