Phylum Arthropoda. Arthropoda is the most diverse animal phylum and includes insects, spiders scorpions, barnacles, crabs, shrimp, and other forms. The Arthropoda also includes a variety of completely extinct groups. All arthropods have an external skeleton and jointed appendages. Class TrilobitaPhylum Arthropoda is the largest phylum in the animal world, and insects form the single largest class within this phylum. Arthropods are eucoelomate, protostomic organisms. Figure 1.

Trilobites have a pair of jointed antennae on the cephalon. The mouth of trilobites have a ventral plate called the hypostome. The body of trilobite is three-lobed and three-segmented; cephalon (head), thorax, and pygidium (tail). Trilobites have compound eyes. Three or more pairs of legs are present in the thorax region of trilobites.

The basic body plan of trilobozoans is often a tri-radial or radial sphere-shaped form with lobes radiating from its centre. Fossils of trilobozoans are restricted to marine strata of the Late Ediacaran period.

Many crinoid traits are like other members of their phylum; such traits include tube feet, radial symmetry, a water vascular system, and appendages in multiples of five (pentameral).
