The southern alligator lizard is one of the largest lizards in Washington. It can be up to 12 inches long, half of which is the long, slender tail. It is usually light or medium brown with variable cross-bars on the back and some black and white spots along the sides. All alligator lizards have a fold of skin along the lower sides, where the scales of the belly meet the scales of the back; this fold expands when the lizards breaths deeply (as in the picture above) or eats a lot. Southern alligator lizards have faint, thin black stripes on the belly that run through the middle of each scale row.
