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.

Arthropods are the most successful group of animals. Their success is measured by having the most species, producing the greatest numbers of offspring, occupying the most habitats, possessing terrific defenses, and being able to exploit new resources.

WOW The phlya arthropoda has the greatest number of species. There have been approximately 1 million species of arthropoda discovered. Scientists believe that there are close to 1 billion species. So there are plenty of species left to be discovered, possibly by you.

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.
