Finding Mammal – Automatic Device Helps Count Migrating Whales

The grey whale is one of the animal kingdom’s great migrators. Every year they migrate in groups called pods, swimming a 20,000 km round trip between Alaskan waters and the warmer Mexican coast close to Baja California. The other major group of grey whales lives in the seas of Korea. Scientists have developed a device to automatically track the formerly-endangered mammal.
