Animal life can vary hugely in any one spot depending on vegetation. A four-mile patch of rainforest could contain up to 400 species of birds, 150 species of butterflies and 60 species of amphibians! Little is known about African forest elephants because of their densely vegetated surroundings.
African elephants are currently the largest animals on land. They have a similar life-span to humans and can live to be 70 years old. The largest living bird is the ostrich. They live in Africa and have the largest eyes of any land animal-each eye is 5cm wide. A group of animals called arthropods includes insects, spiders and crabs. The largest ever was a sea scorpion called Jaekelopterus which could grow to 2.5m long, but it went extinct millions of years ago.
