Abstract

The disparity between the size of the bony pelvis of a pregncant free-tailed bat and the single full-term fetus is so great that in order for birth to occur the interpublic ligament has to stretch to more than 15 times its original length. It is a living elastic band that contains an abundance of elastic fibers.

摘要

怀孕的游离尾蝠的骨盆大小与单个足月胎儿的大小差异如此之大，以至于为了实现分娩，耻骨间韧带必须拉伸至其原始长度的15倍以上。它是一条有生命的弹性带，含有大量弹性纤维。
