Copperhead (Agkistrodon contortrix) - Endangered
Description: 24 - 36 inches. Copperheads are copper colored, with alternating bands of lighter and darker shades. The bands are narrower near the center of the back and become wider as they go down the sides of the body. The bands may not always line up along the center of the back, giving the appearance of triangular blotches. The head is shaped like a spade, and the eyes have vertical, cat-like pupils.
Similar Species: No other snake in Iowa has a look similar to Copperheads, but Western Fox Snakes are often mistakenly identified as Copperhead due to the copper coloring its head. All non-venomous snakes in Iowa have round pupils.
