An X-ray style illustration of an elephant, focusing on its skeletal structure

An X-ray style illustration of an elephant, focusing on its skeletal structure. The image should clearly display all four of the elephant's knees, with detailed and accurate anatomical representation. The bones and joints should be highlighted, with the rest of the elephant's body shown in a translucent style to emphasize the skeletal features. The background should be clean and minimalistic, allowing the X-ray illustration of the elephant's knees to stand out clearly.
