Notice in the picture above, the moccasin has a band along the side of its face. That's the best wat to tell. You don't have to get too close to see it. Rattlers have that too. The brown water snake and banded water snakes are often killed, people thinking that they are a moccasin. Keep in mind that water moccasin can have a varied pattern and colors. The one pictured above is somewhat of a juvinile, which will darken over time. Btw, those pygmy rattlers are everywhere. EVERYWHERE!
Oh great!
What's amazing is that I do not see nearly the number of poisonous snakes than I used to. In the yard, on the road, anywhere. And I know they are here.
