Here's a throwback to the largest Smooth Greensnake(Opheodrys vernalis) I've ever seen. I found it with @joshua.v.feltham while doing a survey for species at risk. This was one of my favourite herping moments of 2016, we observed 4 Smooth Greens within a radius of less than 10 meters and in a matter of less than 20 minutes. A software was used to measure the length of the individual post survey. This monster was 548mm (21.6") total length and 421mm(16.6") snout to vent. These snakes hibernate communally which is why we found so many close together, we likely found their hibernaculum.
