Agkistrodon conanti — Florida Cottonmouth
In 2014, Burbrink and Guiher split Agkistrodon conanti from Agkistrodon piscivorus, and eliminated the other previously distinguished subspecies.
Few sights are as fine to see as a nice fat motionless snake-shaped object near the edge of a nearly trafficless road. Especially just a few minutes after seeing the same kind of object near the edge of the crazy busy Tamiami Trail, where it was impossible to stop and take photos, even though the desire to stop and take photos was high, because this particular type of fat motionless snake-shaped object was a type heretofore unseen by the observer.
I swear this snake was not photoshopped onto a different background, though it sure looks like it was.
This particularly beautiful cottonmouth was exhibiting thigmothermy on the warm late-afternoon asphalt. Thanks to Peter May for teaching me this excellent word.
These are a pre-sundown and post-sundown pair of cottonmouths from a 9-cottonmouth night.
