Notes:
There are constant morphological differences between the bony pelves of adult males and females that constitute a sexual dimorphism. A convexity along the caudal border of the ischiopubic ramus and a bony projection bordering the pubic joint are present only in the male. The pubic joint in the male is a typical symphysis, whereas in the female it consists of an interpubic ligament interconnecting the coxal bones. The ligament contains an abundance of elastic fibers interspersed among collagenous fibers. The disparity between the size of the pelvic birth canal of the pregnant bat and the single full-term fetus is so great that during parturition the interpubic ligament stretches to more than 15 times its original length.
