Arthropod
In zoology, an arthropod was the lifeform classification for any type of multi-legged invertebrates, with a segmented body with paired appendages, and an exoskeleton. Species of this type included, among others, insects, arachnids, and crustaceans. 

After Ensign Brad Boimler's mission to Dansk, where he was going to "wrangle giant centipedes," Beckett Mariner responded to the news of the otherwise dangerous mission, "Aw, sorry, man. No getting eaten by an arthropod today."  ()
