The ability of juvenile black iguanas, Ctenosaura similis , to discriminate between the chemical cue of an unfamiliar and a familiar conspecific was tested. Lizards directed significantly more tongue extrusions toward the chemical cue of a size‐matched conspecific with whom they had never interacted than the chemical cue of a size‐matched conspecific with whom they had interacted for 3 d. We consider the possibility that the social relationship between familiar associates may explain variation in the direction and degree of response to unfamiliar vs. familiar chemical cues.
