Estimating the total number of animals on Earth is challenging, but recent studies suggest there are approximately 20 billion to 1 trillion individual birds, alongside an estimated 100 billion to 1 trillion mammals. Invertebrates, particularly insects, are even more numerous, with estimates suggesting there could be around 10 quintillion (10^18) individual insects. Overall, the total number of animals, including all species across various habitats, could range from several trillion to over a quintillion.
