Electronic Tagging and Tracking Marine Animals Supports Conservation

Understanding and predicting animal movement is important as it is central to establishing effective management and conservation strategies [1]. Until relatively recently, studying the movements and behaviors of highly migratory marine species (turtles, sharks, whales, penguins, seals and billfish) have been challenging due to the logistical and technological constraints of working in aquatic environments. However,…
