A research paper published last September in Behaviour found evidence that common garter snakes were able to distinguish their own scent from that of a littermate fed the same diet. The implication is that garter snakes are able to recognize themselves. Is this the chemosensory equivalent of the mirror test—evidence that even garter snakes have theory of mind? That’s proving controversial: see the National Geographic coverage. In any event, new research continues to suggest that snakes are smarter and more social than we previously thought (previously). Meanwhile, our 23-year-old California kingsnake decided to bite himself while his cage was cleaned yesterday: he, at least, still seems to have trouble recognizing himself (kingsnakes are really stupid).
