Arthropods in film 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 arthropods, including such familiar animals as ants, spiders, shrimps, crabs and butterflies. Early 20th century films had difficulty featuring small insects due to technical difficulties in film-stock exposure and the quality of lenses available. Horror movies involving arthropods include the pioneering 1954 "Them!", featuring giant ants mutated by radiation, and the 1957 "The Deadly Mantis". Films based on
Annelid Annelids are members of the protostomes, one of the two major superphyla of bilaterian animals – the other is the deuterostomes, which includes vertebrates. Within the protostomes, annelids used to be grouped with arthropods under the super-group Articulata ("jointed animals"), as segmentation is obvious in most members of both phyla. However, the genes that drive segmentation in arthropods do not appear to do the same in annelids. Arthropods and annelids both have close relatives that are unsegmented. It is at least as easy to assume that they evolved segmented bodies independently as it is to assume that the ancestral protostome
