The giraffe is under severe mechanical condition caused by the own special proportion. Several mechanical adaptations have been mentioned about giraffe's body. In particular, giraffe's neck can carry large moment and move flexibly. Both of high strength and high flexibility is achieved on the structure of giraffe's long neck. We focused mechanical strength of giraffes neck. We studied structural characteristic of the giraffe's cervical vertebra and analyzed stress distribution of the vertebra by FEM based on CT image to consider its mechanical adaptation. In addition, we analyzed stress distribution of the human's lumber vertebra to compare with one of the giraffe's cervical vertebra.
