The posterior surface of baby Elephants' ears is red because of a rich plexus of veins beneath the thin baby skin. This provides the means by which all elephants ventilate their body heat. Ear-flapping augments the heat dissipation. As mentioned previously, the wrinkled skin is caused by long immersion in the amniotic fluid. The gestation period for African Elephants is 22 months.
