What is an Arthropod?. Phylum . Arthropoda. Most diverse and successful animals of all time. Segmented body, tough . exoskelton. , jointed appendages. Classified based on number and structure of their body segments and appendages. When Carl Linnaeus first created his method for organizing animals, he had just two families of invertebrates:. . Insecta. (insects) and . Vermes. (worms).. Since that time, scientists have found more invertebrates and have created more classifications. We will talk about six main categories or families of invertebrates.. Crown-of-Thorns Star Fish. By Joe Baartz. Biological Classification. The binomial name for the Crown-of-thorns starfish is called ‘. A. canthaster . P. lanci’~ Linnaeus, 1758.. Kingdom: Animalia. By: Amanda Brainerd. Endoskeleton . Five-part radial symmetry.
