Abstract
The ability of juvenile black iguanas, Ctenosaura similis, to discriminate between the chemical cue of an unfamiliar and a familiar conspecific was te sted. Lizards directed significantly more tongue extrusions toward the chem ical 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 inte racted for 3 d. We consider the possibility that the social relationship be tween familiar associates may explain variation in the direction and degree of response to unfamiliar vs. familiar chemical cues.
