Fish Can Learn Basic Math

Fish may not be able to calculate complex stuff like us humans, but that doesn't mean that they can't learn math. This recent study reveals that fish, specifically bony cichlids and cartilaginous stingrays, can add and subtract small numbers. While this may be a surprise to many, the researchers were not surprised by the findings. Fish have already been shown to distinguish between relative quantities before. However, this study reveals how fish, without fingers, manipulate small numbers.

Not all cichlids and stingrays finished their training. However, those who did are said to have "performed well above chance." This means that fish are not stupid, contrary to statements used to excuse awful fishing practices.
