This guy? Very easy to photograph, though I advocate stepping over sleeping snakes, rather than (as the well meaning proceeding person had done) trying to prod them off the path with a stick. Little guy, and bright pink mouth lining, but this does not seem to suffice for online identification purposes.
This guy? nearly impossible; an apparently traumatized skink, hiding under the boards of the pond observing platform near the visitor's centre at Point Pelee.
