Green Turtle - Chelonia mydas - QA89291
31 October 2017
Raine Island
This turtle was tagged with a satellite tag and two titanium flipper tags by researchers once she finished laying on the 31 October.
Her curved carapace length was 106.0cm. Between 31 October 2017 and 23 January 2018 she laid 8 clutches of eggs. In between, she has been very active, moving beyond Raine Island Reef to spend time at Saunders Reef. In highly unusual behaviour, she left Raine Island around 11 December and headed north to the Torres Strait, swimming past Adolphus Island, seemingly beginning her migration earlier than expected. But she then returned to Raine Island around 17 December and continued to lay eggs. Researchers are watching this unusual behaviour with interest and looking forward to finding where her feeding grounds are.
Her name will be chosen by Mer School students.
