Fish Are Taught Tricks
Fish have memories, and can be taught to perform tricks, according to Dr. Mieczyslaw Oxner, ichthyologist at Europe’s oldest aquarium, in Monte Carlo. Two months are required to train a fish to eat out of your hand, Dr. Oxner declares. Below, some of his finned pupils are shown “jumping” through a hoop.
