From the Paper:

"The arrangement of animals in this phylum is quite varied. These creatures are usually divided into four classes: Trilobita (trilobites, which are now extinct, but the fossils look like flat beetles or sea creatures), Chelicerata, (which include spiders and scorpions, mites and ticks, horseshoe crabs, daddy-longlegs, and other animals with eight legs), Crustacea, (which include crabs, lobsters, shrimp, and other sea creatures), and Uniramia, (which include insects, millipedes, centipedes, and insects like these). These four main classes hold literally millions of insects and members. Since there are so many diverse insects and spiders on the planet, and scientist know they have not all been discovered, many people believe there are thousands that are not yet classified, and the entire class holds many millions of animals. Estimates place arthropods at about 80 percent of all known animals on Earth (Tatner). Within these four classes, the animals are broken down even further into numerous sub-classes."
