All animals which have a spine, or backbone, are classified in the phylum Chordata.
Members of the phylum Chordata are bilaterally symmetric, deuterostome coelomates, and the vertebrate chordates display segmentation. Hemichordata, which includes the acorn worms, has been presented as a fourth chordate subphylum, but it now is usually treated as a separate phylum. Chordates form a phylum of creatures that are based on a bilateral body plan, and is defined by having at some stage in their lives all of the following: 1  A notochord, a fairly stiff rod of cartilage that extends along the inside of the body. Classes Found In The Phylum-Chordata All chordates have a number of structures in common: A notochord (noto = the back; chord = string) is present in all embryos, and may be present or absent/reduced in adults. This is the structure for which the phylum was named. The notochord is a rod-like structure that forms the supporting axis of the embryo and gives birth to the vertebral column in vertebrates. Chordates are sometimes referred to as “ vertebrates ” because most possess a backbone with vertebrae. Chordata is the phylum of animals that have a number of features in  common, but most notably a notochord (which is called a spinal cord  in humans because we have a backbon … e, a spine, through which it is  routed). All the vertebrates (animals with a backbone) are grouped  within this phylum. The phylum Chordata is a taxonomic group. All animals which have a  spine, or backbone, are classified in the phylum Chordata. There  are three subphylums in Chordata: Uroch … ordata (tunicates),  Cephalachordata (lancelets), and Vertebrata (vertebrates) The phylum Chordata contains all animals that possess, at some point during their lives, a hollow nerve cord and a notochord, a flexible rod between the nerve cord and the digestive track. The phylum Chordata is divided into three subphylums: Urochordata (tunicates), Cephalachordata (lancelets), and Vertebrata (vertebrates). Chordata is a phylum in the classification system used in biology.  Characteristics of organisms in the phylum Chordata is that they  have a nerve, or spinal, cord and phara … ngeal slits. 3 people found this useful. The phylum Chordata is a taxonomic group.

Phylum Chordata is the only phylum where all the members have a  backbone.

The first two phyla are very small containing only about 2,000 species total. Tunicates are marine animals that only show the attributes of the chordata phylum in the larva stage, and when they turn into adults lose the notochord and nerve cord. Adult tunicates look like small sacs around 3 cm tall attached to the ocean floor.

The word phylum (plural: phyla) is a category used to classify marine organisms. In this article, you can learn the definition of phylum, how it is used, and examples of phyla used to categorize marine life.
