the spine and femurs
the femurs and the sacrum
Having femurs that are too long could disadvantage a grasshopper by making it harder to maintain balance and stability while jumping or moving. Longer femurs may also increase the energy expenditure required for locomotion, making it less efficient. Additionally, excessively long femurs could hinder maneuverability in dense vegetation, making it easier for predators to catch them.
There are 62,305 different type of skeleton.
A rodent skeleton is not different from a vole skeleton. A vole skeleton is just one of many types of rodent skeleton. That is because voles are a type of rodent.

Leg bones including Femurs
Frogs have several types of bones that can be categorized into two main groups: axial and appendicular skeletons. The axial skeleton includes the skull and vertebral column, which protect the brain and spinal cord, respectively. The appendicular skeleton consists of the limbs and pelvic girdle, aiding in locomotion. Frogs also have unique adaptations in their limb bones, such as elongated femurs and fused bones, to enhance jumping capabilities.
