Fish Has Numerical Ability? Yes or No?

Wow, its the first I knew this news. I think this is useful, so I share it with you ^^
I just knew that not only us have that ability, but fish has it too! Dou you want to know what that kind of fish? Can you guess it? ^^

It's Angelfish. Yapp, the scientists have proven this through research to it. Then, Scientists concluded that the fish can distinguish a lot or a little plus be able to count from 1 to 3.

Gerlai and Luis Gomez-Lalpaza from the University of Oviedo, Spain, attracted by the notion that fish angels choose to join the great herd when in a foreign environment. They do so for the sake of security.

Gerlai and his team put the fish in a special tank. Fish is faced with two herds with different amounts. The researchers then recorded the selected herd fish.

As a result, angel fish are able to choose a larger herd when the difference between the two herd number is doubled. When the difference in amount is less than two times, the choice of fish can not be predicted. With these findings, the researchers drew the conclusion that the angel fish can predict the number of flocks.

Aside from being able to predict the amount, angel fish can also be more precise count. "For example, fish can distinguish between 2 and 3," Gerlai exemplifies. "This shows the calculation of individual ability, not just estimate the amount," he said. Gerlai also explains, numeracy angel fish is limited only to 3.

Scientists guess, numeracy skills in these fish have no advantage for the fish. "Hence, this ability does not evolve," said Gerlai.

Unlike numeracy skills, the ability to predict the number of herds have advantages for angel fish. They choose their predictions herd more for security and the search for food. (National Geographic Indonesia / Alex Pangestu)
