The study in 2013 on the effects of social isolation on juvenile veiled chameleons sparked numerous discussions on the needs of lizards for social interaction. Much of the media coverage made leaps that were not part of the study. For example, both the titles "Lizards Need Social Lives Too" and "Early Isolation Makes For a Dull Chameleon" were inaccurate portrayals of the results of a study that sought to show that social interaction affected behavior.
I wrote a analysis that can be found below and am interested in the experiences and opinions of those here as they relate to juvenile behavior in groups or isolation. (Note: The image is of panther chameleons and the study was with veiled chameleons. The behaviors and conditions are parallel)
