acoustic tags

Acoustic tags are small devices attached to or implanted in animals to track their movements and behavior. They emit sound signals, or "pings," that can be detected by underwater microphones called hydrophones. When a tagged animal moves through the area, researchers can monitor its location, activities, or migration patterns based on these signals. Acoustic tags are commonly used in marine biology to study fish, sharks, or marine mammals, helping scientists understand their habits and make conservation decisions without disturbing the animals significantly.
