The most important step for a pregnant whale in
order to give birth must be to eat as much as
possible. The total time it takes for a whale
to develop in its mother prior to birth (called
gestation time) depends on the species of
whale but it ranges from 10-18 months. This
is longer than human gestation time (9 months).
During pregnancy the mother will continue to
feed to support the growth of the whale fetus.
Some whales migrate long distances during that
time, while others stay within the same habitat.
Lets take the blue whale for example; it
is a truly incredible animal, the largest to ever
exist! Some of the biggest blue whales are longer
than two school buses parked front to back. A
baby blue whale (called a calf) takes 10 months to
develop in its mother and when it is born it will
be bigger than a car. That’s a big baby! The
calf requires a lot of energy to grow and once it
is born will drink 100 gallons of milk per
day. So it is important that the mother gets
lot of food to support the growth of the calf
during gestation, and to produce enough milk to
feed the calf once it is born.
