Wait a minute…is somebody really saying that fish can do math? Yes. Yes, they are. Check out this study:
BONN, Germany (StudyFinds.org) – Apparently, one plus one equals tu-na. A new study reveals that fish are capable of doing simple math problems, just like people!
Researchers in Germany have found that cichlids and stingrays are both able to recognize and calculate small quantities without really having to count them — just like a person looking at their change on a table.
“We trained the animals to perform simple additions and subtractions,” explains Dr. Vera Schluessel from the Institute of Zoology at the University of Bonn in a release. “In doing so, they had to increase or decrease an initial value by one.”
Although some call fish the “dunces of the animal kingdom” because of their memory span — which can last just three seconds — the new study revealed their capacity for complex sums, adding and subtracting from one to five.
