"As part of a site fidelity and migration study, this Hawksbill Sea Turtle has a small transmitter that sends its positions to orbiting satellites so that scientists can learn more of their habitat needs to better protect this endangered species," wrote Jake Levenson of his image, a winning selection in the Portraits of Planet Ocean Flickr contest. Satellite tags can track sea turtles like never before, helping with research on where newly hatched sea turtles go and how different populations hunt. See more winning photos.
