Baby turtles tagged, charting 4,500 mile journey
A group of wild baby turtles younger than six months have been tagged for the first time, allowing scientists to track their 4,500 mile 70 day-long journey.
The 17 swimmers, the youngest sea turtles ever to be satellite tagged by scientists, travelled the same distance as London to Mumbai.
Using data transmitted by the tags they were able to map every movement of the loggerhead turtles, captured from their beach nests in Florida.
The breakthrough was made possible by the scientific team customising tiny nine gram tracker tags normally used for birds.
They made the gadgets waterproof and then glued them to the backs of their turtles, aged four to six months old, before releasing them 10-miles east of Palm Beach.
Jeanette Wyneken, Associate Professor of Biology at Florida Atlantic University and research professor, Kate Mansfield, said they were „excited“ by the results.
„Previously we have never known what these young turtles do once they leave their beach nests and swim off into the ocean,“ said Prof Wyneken.
„It was really exciting but it was important to us that the tags did not stop them from behaving normally.
„Thankfully they acted as if there was nothing attached to there backs at all.
„Seaweed is an important habitat for the turtles and they had no problem moving around it.“ …
