Fish have generally not been considered as intelligent animals. Yet recent research on fish brains and behavior has revealed that some fish are highly intelligent. New findings have shown that some fish can recognize their own reflection in a mirror, identify individual fish by the differences in their facial patterns, and are even believed to have feelings of compassion. In this episode, we'll start out by exploring the surprising intelligence of fish. Then later in the program, the Takumi / J-Innovators corner will feature the novel development of 3D food printers.
