Résumé | Two individuals displaying mixed features of the colour patterns distinctive of Arothron meleagris and A. nigropunctatus were observed on the fringing reef at Réunion Island, between September 2012 and August 2013. Because many hybrid fish have been first identified through colour patterns that are intermediate between two known species, these pufferfish individuals were suspected to be hybrids. However, since no specimen was collected for examination, a hypothesis that the observed individuals could be hybrids is based on comparison of their colouration with colour patterns documented |
