How many critters are exist?

Answer 1

The term "critters" generally refers to small animals or creatures, and it can encompass a vast range of species, including insects, arachnids, amphibians, and small mammals. There are millions of critter species worldwide; for example, there are over 1 million identified insect species alone. Estimates suggest that there could be anywhere from 5 to 30 million total species on Earth, many of which would fall under the broad definition of critters. Thus, the exact number of critters is difficult to determine but is likely in the millions.
