From one-centimetre foetus to birth as a calf weighing 118 kilograms.Its astonishing !22-month gestation - the longest of any mammal.At 16 weeks, the foetus begins to look like an elephant as it develops a trunk. Two weeks later it is seen exercising its trunk and legs, and ears that already detect sound start to grow.By 12 months, the foetus is a replica of what will emerge 10 months later £ except it is just 45 centimetres long.
