In the Womb: Extreme Animals

Animal Fact Guide — Fri, 08 May 2009 19:50:53 +0000

We recently reviewed National Geographic’s book, In the Womb: Animals, which followed the birth journey of a golden retriever, bottlenose dolphin, and Asian elephant. Intertwined with the main stories were glimpses into the peculiar behavior and development of kangaroos, sharks, penguins, and wasps.

Now we have the opportunity to learn more about the reproductive cycle of these extraordinary creatures. This Sunday, May 10 at 9pm, the National Geographic Channel is airing a full documentary called In the Womb: Extreme Animals. Using 4D ultrasound images and fetal imaging techniques, the two-hour special will highlight bizarre, sometimes gruesome, activity such as the parasitic wasps’ larval development inside the body of a young cabbage white caterpillar and the lemon sharks’ embryonic cannibalism.

Watch a clip of the documentary featuring how a penguin fetus uses a complex and clever adaptation to get oxygen while inside the egg:
