The Arthropods, the largest animal phylum, includes insects, spiders, crustaceans, and others. Comprehensive information from UC-Berkeley website.

Molting Animals Form Clade Ecdysozoa Arthropods have a rich fossil record, but their phylogenetic relationships remain unclear. Taxa proposed to be sister groups include Annelida, Onychophora, Tardigrada and others, but hypotheses of phylogenetic relationships have been conflicting.

5. Arthropoda.
The arthropods are far and away the dominant form of life on earth today, and presumably were so in the past as well. Most lack a mineralized skeleton, which probably accounts for their typically poor fossil record. There are, however, taxa within the Arthropoda with fair to quite good records.
Category:
Arthropods are easily the most diverse group of animals on the planet. The number of insects alone is greater than all the other animals combined. The fossil record shows a similar trend (at least for some groups): the number of trilobite species is greater than 10,000.
Category:
The arthropods are the most numerous of the animal phyla, including nearly one million known species (and more are being discovered all of the time!) Arthropods are found in almost all conceivable habitats, and feed on a great variety of materials.
