Arthropods in film seem heroic and sympathetic when faced against the big, big world. Another reason is counterpoint to the reason for using arthropods in horror films: whereas horror movies play upon the instinctive negative reaction humans have towards insects and arachnids, these animation films make something that is different and strange seem real, approachable, and sympathetic, thus making it comforting. Arthropods in film Arthropods, mainly insects and arachnids, are used in film either to create fear and disgust in horror and thriller movies, or they are anthropomorphized and used as sympathetic characters in animated children's movies. There are over 1,000,000 species of
Threatened arthropods of endangerment beyond the amount of land consumed by the fragmenting agent. As an example, consider the construction of a highway, whose width is an effective barrier to arthropod migration. Many arthropods never migrate more than about 200 feet from their place of birth, so a freeway or dual carriageway effectively fragments many arthropod colonies such that they cannot interact. Studies have shown the greater vulnerability to extinction where habitats are fragmented. The following is a very small fraction of the potentially hundreds of thousands of endangered arthropods, limited to species which have been formally recognized as to their special
