Big babies

Hi friends,  
The African elephant has the longest pregnancy of any mammal. She carries her baby for an average of 660 days. When baby is born it weighs 90-120 kg (195-265 lb). A baby blue whale is even bigger. It weighs 2,000 kg (4,409 lb) and is 7m (23ft) long. It puts on weight at astonishing rate of 90 kg (198 lb) a day. Thank you.
