Over 95% of Australia’s animal species are invertebrates. They represent an extraordinary diversity, found in nearly every habitat and ranging in size from 0.1 millimetre to over 13 metres. They perform crucial tasks in our ecosystems, acting as pollinators, seed dispersers, nutrient recyclers, and much more. Invertebrates are fascinating, often beautiful, and fundamental to life as we know it.
