Phylum Chordata - Characteristics And Classification.
Chordata - Chordates - Animalia more on vertebrates. A colony of sea squirts, Clavelina moluccensis, the bluebell tunicate. This is a chordate as the free swimming larval stage has a notochord, but is not a vertebrate, the notochord is lost in the adult which becomes a sessile (fixed to the spot) filter feeder. picture - Nhongood, used under CC3 Attribution Share Alike unported License.

The phylum echinodermata is divided into many classes. It includes asteroidea, ophiuroidea, echinoidea, holothuroidea and crinoidea. The asteroidea are also known as the star form organisms. There body is flat and have short.
In many of the non-vertebrate chordates, such as tunicates and cephalochordates, the clefts and arches are elaborated as straining devices concerned with capture of small food particles from water. In typical fish-like vertebrates and juvenile amphibians the walls of the pharyngeal clefts develop into gills that are organs of gas exchange between the water and blood. In adult amphibians and.
All chordates have a notochord that is present during some or all of their life cycle. A notochord is a semi-flexible rod that provides structural support and serves as an anchor for the animal's large body muscles. The notochord consists of a core of semi-fluid cells enclosed in a fibrous sheath. The notochord extends the length of the animal's body. In vertebrates, the notochord is only.
Classification taxonomies allow for animals to be classified into groups of organisms with similar characteristics. Two examples of these classifications include chordates and non-chordates.
