Now we come to pregnancy. Ultrasound is very common in humans
to detect pregnancies in women. But an elephant is much bigger
and you need a special technique to find such pregnancies by ultrasound.
That's an African culled elephant, and I use it to show the structure
inside. The fetal cavity is very round, it's not elongated like
in horses or cattle, and it's attached only with this stripe,
which we have seen before which makes a scar in the uterus.
