The Essex Robotic fish is a very realistic swimming fishbot. They are approximately fifty centimeters in length, 15 centimeters high and 12 centimeters wide.
The above video shows just how realistic the motion is. The robots are covered in light-reflective scales, as well as tiny sensors that provide information about the distance from obstacles.
I covered the fishbot carp in a previous story (Robofish Autonomous Fish-bot At London Acquarium); the robocarp seems like a good start on the Mitsubishi turbofish predicted by Michael Swanwick in his 2002 story Slow Life:
The Mitsubishi turbot wriggled, as if alive. With one fluid motion, it surged forward, plunged, and was gone.
Lizzie switched over to the fishcam.

BTW, be sure to turn on your sound to get the euro-retro music track from the video.
