So why post it? I can't say why I am posting a picture except for the modern 'pics or it didn't happen' complaint. Mostly, I saw this turtle on Feb 1 and the air temp was 1 Celsius. A few years ago, I was surprised to see turtles in Ontario Canada swimming early, but that was late April I think, not the beginning of February.
Some information on Slider turtles, spread around the world via the pet trade.
