Researchers create robotic fish that can swim underwater on its own

Observing fish in their natural ocean habitats goes a long way toward understanding their behaviors and interactions with the surrounding environment. But doing so isnt easy. Using underwater vehicles to get a look at these species is one option, but they often come with a slew of limitations. Some are loud and use propellers or jet-propulsion that disturb fish and their surroundings. And many are designed in a way that doesnt allow them to blend in with the marine environment. Cont…..
