Ladies, can you imagine being pregnant for nearly two years?! That's how long female elephants are pregnant for and keepers at Melbourne Zoo have announced they've started monitoring Asian elephant, Num-Oi, as she enters the final stages of her second pregnancy. After the tragic death of her first calf, it will be nice to see her with a new baby. Hope all goes well. She's expected to give birth some time between now and the end of May.
