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
Arthropleuridea were common at the time and may have burrowed in the undergrowth. They were either herbivores or detritivores. Besides their size, their most distinguishing features were their legs with eight segments (as many as 30 pairs) and extremely tough exoskeletons. There is no evidence of spiracles, so the animals must have used lungs or gills for respiration. Most arthropleurideans are thought to have been terrestrial, although, without any known respiratory structure, terrestriality is assumed only by analogy to modern arthropods. Early forms, however, including "Eoarthropleura" (order Eoarthropleurida), appear to have been aquatic. For this reason, some question Arthropleuridea's inclusion among
