Frog skeletal system question?

The frog has many skeletal adaptations. Tibia-fibula is larger and has more surface area to allow for more muscle attachment and therefore leading to the ability to jump higher and further as well as swim faster. Digits on the frog are also longer to increase swiming power and speed. The frogs urostyle is fused to increase strength and decrease the weight of the for as well as make the skeletal structure more sound.
