Notophthalmus viridescens - The Red Spotted Newt. Newts belong to the salamander family. Not all salamanders are newts. 'Newt' is a common term used for salamanders that spend most of their life living on land.
The skeletal structure of a human being (left) and of a gorilla (right). Several differences allow the human being to walk erect on two legs with a striding gait rather than move in a knuckle-walking fashion like the gorilla. In the pelvis these differences include shorter ischia, a broader sacrum, and broader, curved-in ilia with a lower iliac crest. In the legs the femurs (thighbones) are relatively long and are set farther apart at the hips than they are at the knees.
