The largest phylum among all animal phyla.
The success of arthropods is probably the result of very helpful adaptations such as
Flexible body segmentation
External and light skeleton
Jointed very adaptable appendages
Many Arthropods undergo a very complex developmental process called
Developmental process where vastly different physiological, morphological, behavioral and ecological stages of an individual will appear sequentially through their ontogeny.
Arthropod classification is based on
Modification of their appendages and body regions.

Incomplete metamorphosis. The development of certain insects that includes three distinct stages: the egg, nymph, and adult (imago) stage. The organism goes through gradual changes with no pupal stage.
Complete metamorphosis. These insect groups go through four stages: embryo, larvae, pupa, and adult (imago).
segment grouped together
These are marine, spiny-skinned, slow moving, voracious animals
Phylum Echinodermata
This phylum has bilateral symmetrical larvae which change into adults that have pentamerous radial symmetry.
This phylum is a true coelomate and deuterostomes
This phylum has a water vascular system unique to the organisms
This phylum has organisms which are coelomates, segmented, deuterostomes, bilaterally symmetric, dorsal hollow nerve cord, longitudinal flexible supportive rod (notochord), pharyngeal gills, and a postanal tail.
Subphylum ____ is the largest and most familiar group of Phylum ____ which have the notochord partially or totally replaced by cartilage or bone.
Vertebrata, Chordata
Vertebrata are seperated by
