Indonesia was created by volcanic eruptions 150 million years ago. Today, there are 155 active volcanoes in Indonesia, and one erupts every day. Heavyweight Komodo dragons throw themselves at each other as they do battle for a mate. On Sulawesi, weird maleo birds incubate their huge eggs in hot volcanic sand and on Borneo proboscis monkeys leap across rivers, trying to avoid falling into the mouths of waiting crocodiles.
