A new study has found that Julidochromis transcriptus, a rock-dwelling cichlid from Lake Tanganyika, use facial recognition to identify friends and foes. J. transcriptus were studied and it was determined that facial patterns play a larger roll than other visual cues in how these fish identify individuals. A study on archerfish concluded that they could discriminate between human faces, but the study on J. transcriptus points to something the fish might use in the wild.

The study is behind a pay wall, but a short synopsis can be found on the New Scientist website. To discuss the study or Julidochromis transcriptus in general visit the Lake Tanganyika Species forum.
