The Superphylum Articulata is a member of the Infrakingdom Ecdysozoa. Here is the complete "parentage" of Articulata:
- Domain: Eukaryota Whittaker & Margulis,1978 - eukaryotes
The Superphylum Articulata is further organized into finer groupings including:
- Phylum (1): Arthropoda
An arthropod is an invertebrate animal having an exoskeleton (external skeleton), a segmented body, and jointed appendages. Arthropods are members of the phylum Arthropoda (from Greek ?rthron, "joint", and p?d?? pod?s "foot", which together mean "jointed feet"), and include the insects, arachnids, crustaceans, and others. Arthropods are characterized by their jointed limbs and cuticles, which are mainly made of a-chitin; the cuticles of crustaceans are also biomineralized with calcium carbonate. The rigid cuticle inhibits growth, so arthropods replace it periodically by molting. The arthropod body plan consists of repeated segments, each with a pair of appendages. It is so versatile that they have been compared to Swiss Army knives, and it has enabled them to become the most species-rich members of all ecological guilds in most environments. They have over a million described species, making up more than 80% of all described living animal species, and are one of only two animal groups that are very successful in dry environments ? the other being the amniotes. They range in size from microscopic plankton up to forms a few meters long. [more]
At least 1,094,118 species and subspecies belong to the Phylum Arthropoda.
