The penis is a soft tissue structure and is not part of the pelvic bone.
An example of a homologous structure that is greatly reduced in size is the pelvic bone in whales. These bones are remnants of hind limbs found in their land-dwelling ancestors, which have evolved to be much smaller and non-functional in whales due to their adaptation to an aquatic lifestyle.
vestigial organs such as a tail bone in humans and a hip bone in whales. also, the skeletal structure of wings of birds, flippers of whales, and hands of humans are all very very similar in structure.

The shape of the pelvic bones and the frontal bones differ.
That is the tail bone.
I think the pelvic is near your hip bone. :D
All the bones in males are heavier than females, including the pelvic bone. This is due the effect of male hormone called as testesterone.
A typical long bone such as the femur contains spongy bone and compact bone. Within compact bone are haversian canals, which contain blood vessels.
The most anterior part of the pelvic bone is the pubic symphisis.
