What is the amount of minibeasts in the world?

Estimating the exact number of minibeasts, or small invertebrates, in the world is challenging due to their vast diversity and the many undiscovered species. Scientists believe there are around 1 million described species, but the total number, including undiscovered ones, could be in the range of 10 million to over 30 million. Minibeasts include insects, Spiders, mollusks, and other arthropods, making them the most abundant group of animals on Earth. Their numbers play a crucial role in ecosystems as pollinators, decomposers, and food sources for other animals.
