This Copperhead Snake (Agkistrodon contortrix) was photographed through glass at the Chattanooga Aquarium. I was glad to finally be able to get this close to a live one (safely!) to get a good picture! Note the hourglass pattern of the dark brown bands on the back, vertical slit pupil in the eye, and the pit between the eye and mouth. This is the most common venomous snake in the eastern United States, however they are the least venomous. They are very well camouflaged, so they aren't often seen in the woods. Copperheads give birth to live young (meaning the eggs hatched inside the mother). These snakes eat birds, small rodents, insects, lizards, snakes, and amphibians. Although the bite of a copperhead is seldom fatal in healthy humans, the venom does cause tissue destruction and must be treated in a hospital. Small dogs can die from being bitten by a copperhead.
