Humans have to carry all of their weight upright and on just two legs. Animals that have four legs to support their weight and their pelvic bones are less massive. We "pay" for this as we are more prone to fractures and other problems of the upper leg bones.

∙ 14y agoThe pelvic bones of a two-legged animal such as a human have to carry his whole weight, divided by two. A four-legged animal such as a pig divides its weight over four legs, so each leg and each pelvic bone has to bear only a fourth of the animal's weight. As the strain on the bones is a half than in the two-legged case, the bones can be less massive.

∙ 13y agobecause animal are different from a human HOW?human bone are longer than a animal bone they has lot of bone than an animal
Wiki User
∙ 13y agoI guess is because the weight of the body distributes equally in four parts meanwhile humans have to equally distribute their weight in two which requires stronger and denser bones
Wiki User
∙ 12y agobecause the body weight is spread out over four legs instead of two
Wiki User

How does the pelvic girdle size of fish compare to those of land animals?
Fish do not have "pelvic girdles" per se. Land animals in large majority have skeletal structures in their hips known as pelvic bones. In humans, men have a narrow pelvic size and women have a wider pelvic size. This is because women bear babies. The circular shape of these pelvic bones are referred to as the "pelvic girdle". Fish, however, don't have hip bones. Living in the water has eliminated the need for the extra physical support those bones would give during pregnancy. Since fish range in size from near-microscopic up to the immense whale shark, the equivalent to the pelvic area would vary greatly in size. Mammals too, range widely in size so comparison is difficult without a more specific question.
