A team of researchers conducted an experiment to test shark intelligence using jazz music.
Researchers from the Macquarie [muh–KWAWR-ee] University Fish Lab in Australia conditioned eight young Port Jackson sharks to associate jazz music with food. They did so by teaching the sharks to go to a feeding area while jazz music was played. Five out of the eight sharks were able to discern the melody of jazz as they swam to the area where the music played.
In the second phase of the experiment, the researchers tested if the five sharks could differentiate jazz and classical music. Findings showed that the sharks had difficulty telling the two genres apart. But generally, the sharks were more partial to jazz music because they still had a tendency to swim toward the same feeding area when the genre was played.
Catarina Vila-Pouca, the lead author of the study, believes that the insights from this experiment can help in analyzing sharks’ learning abilities. She is hopeful that becoming attuned to these abilities can eliminate negative perceptions of sharks and can ultimately lead to their conservation.
Aside from jazz music, sharks were also found to have the ability to recognize shapes. In a study published in 2014, a researcher from a German university placed eight juvenile gray bamboo sharks in a tank and displayed images of a triangle and a square on each side of the tank. Half of the sharks were trained to select a triangle, while the rest was taught to choose a square. Upon recognizing the shapes, the sharks received food as a reward.
