Robotic coelacanth fish mimics how the fish swims in the ocean at an aquarium in Japan

Something is fishy about a new sea creature at Aquamarine Fukushima in Japan. The sea creature is not alive- it is a robotic coelacanth, measuring about 1.2 meters long. Robotic coelacanth fish is on display at the permanent exhibition called The World of Coelacanth on the first floor of the aquarium in Iwaki, Fukushima Prefecture, Japan. The aquarium is famous for its study of coelacanths, a prehistoric fish that was once thought to be extinct. Researchers captured images of live coelacanths in waters off Indonesia using a remote underwater camera.

Those images were used in reproducing the movements of the life-size robot, which was completed in conjunction with researchers at Kanazawa Institute of Technology. When visitors press a button on the case, the robot’s six fins are activated, mimicking how the fish swims in the ocean.
