Whale Tracking Device

This radio device is used to track North Atlantic right whales. Suction cups hold the device to a whale's back, where it records data such as depth, water, temperature, and underwater sounds. These tags can be used on many species of whales, including blue whales and humpbacks, and other versions have been used to study many other ocean animals. Read more about right whales in the Tale of a Right Whale slideshow.
