Female bats can control when they get pregnant and give birth
Something human females could use!!To ensure external conditions are optimal for a newborn bat, mother bats are equipped with a variety of biological tactics that allow them to put off fertilization, implantation or development of the fetus.In some species, mating will occur in the fall, but females will store sperm in their reproductive tract before finally fertilizing their eggs when spring arrives. In other species, the egg is fertilized immediately after mating, but instead of implanting to the wall of the uterus, it floats around until favorable conditions arrive. Yet another adaptation exhibited in some bats is delayed fetus development, in which fertilization and implantation occurs as usual, but the fetus remains in a dormant state for a long period of time.These tactics, which contribute to the slow birth rate of bats, are timed to coincide with high production of fruit or insects in the environment.
