In the Galápagos National Park, specialists are carrying out work to track hammerhead sharks to understand the migratory routes of fish.
The technique used is acoustic trackers. They determine a position by emitting a sound that is picked up by a receiver. The time elapsed from sending to receiving allows the calculation of the distance between sender and receiver. Watch the video about the work being done in this Pacific paradise.
