With over 5,000 media donors from around the world contributing valuable films and photographs, ARKive has created a comprehensive audio-visual biological profile for thousands of animals, plants and fungi, depicting typical species characteristics, life cycle, and behavior – what it looks like, where it lives, how it behaves, and why it is special. Teachers and students can download this media and related content for classroom use, free of charge!
