A new research article has come up with some interesting finding in facial recognition by cichlids. The experiments were conducted with Neolamprologus pulcher, a schooling cichlid from Lake Tanganyika. The study found that when presented with images of different Neolamprologus pulcher, they could quickly recognize them as familiar or unfamiliar. A quick glance, < 0.5 seconds, was all that was needed for N. pulcher to identify recognizable facial features of familiar fish. The speed of recognition is comparable to that of primates, including humans. To read about the study visit PLOS.org. Discussion on N. pulcher can be done in the Lake Tanganyika Species forum.
