Creature 2: Animal Anatomy

Above are sketches of the skulls of a Rhesus Macaque (top left) and saimiri sciureus (other two) or other know as a Common Squirrel Monkey. The Rhesus Macaque has strong bone and large teeth for defence. The Squirrel Monkey has a smaller more fragile skull with small proportions apart from the eye sockets.

Above is a skeleton sketch of the Common Squirrel monkey and its hands. Its hard are made perfect for gripping onto branches. It has a long spine leading into its tail for balance as it is jumping from branch to branch.
 

This is the muscle structure of the Common Squirrel Monkey. It is a very nimble creature but still quite athletic for its day to day lifestyle.
I feel that a mixture of the Common Squirrel Monkey's body which is made for high amounts of climbing, jumping and leaping, mixed with the skull features of the Rhesus Macaque will be a good reference for my creature anatomy.
