Threatened arthropods and described. The total number of living arthropod species is probably in the tens of millions. One conservative estimate puts the number of arthropod species in tropical forests alone at six to nine million species. As a consequence of all of the above, most published estimates of the total number of endangered insects and arachnids are probably low by at least an order of magnitude. Conservatively at least eighty percent of all living animal species are arthropods. Since arthropods constitute the majority of the faunal biomass on Earth, their role is vital to the survival of large numbers of insectivores
Arthropods in film oversized arthropods are sometimes described as big bug movies. Arthropods used in films may be animated, sculpted, or otherwise synthesized; however, in many cases these films use actual creatures. As these creatures are not easily tamed or directed, a specialist known as a "Bug Wrangler" may be hired to control and direct these creatures. Some bug wranglers have become famous as a result of their expertise, such as Norman Gary, a champion bee-wrangler who is also a college professor, and Steven R.
