The chordata, also known as chordatae, is a spongy, wet, thin-skinned chordate. The word chordata is derived from the Greek word chordates, meaning “cheshire”. A chordate is not a true chord because it has no root in the guitar body. This chordate is actually an accessory (or “amen”) of a guitar. A chordate possesses many chordato phenomena, such as:
A chordate has several characteristics that differentiate it from other chordates. A chordate possesses a notochord (a chord on the head of the shaft). All chordates have 5 common drumming-style chordiferous synapses, which are found in each chordate. All chordates have a dorsal hollow nerve chord, which is present in every chordate.
Phylum chordata also has several other unique characteristics. chordata refers to a class of chordophores that have developed in chordata embryos and held on to them through the subsequent phase of their development. These chordophores are called “tunicates” by those in the music industry. chordophores usually consist of four digits, namely an alphabetic character plus two to seven nonalphabetic characters. The first two digits of a chordophore constitute its rank (i.e., first, second, third etc.) while the last two digits identify the particular chord that the organism is performing.
This class is composed of both chordophores and tunicates. It is composed of both chordates and craniates, both of which have evolved separately. chordata and craniates share common characteristics and function as described above. However, chordata and craniates differ in the way they retain information from the previous phase of their evolution. Specifically, chordata retains reproductive information and memory from the initial stage of their evolution, while craniates (and all chordates, for that matter) retain such information and memory from both the pre and post-stage events.
Among the notable phylum chordata representatives are the so-called “sperm whales” and “placental mammals.” Among the placental mammals, the placenta is perhaps the most prominent member of this class. Placental mammals generally retain a well-developed digestive system, but it is present in chordata only in its early and incomplete stages. Its development is incomplete in chordata because the organs of reproduction are developed in other areas. In chordata, however, it appears that the placenta provides the necessary environment for the development of the other organs. In fact, it accounts for a large proportion of chordata, even after the expulsion of the sperm whale and the complete regeneration of its anatomy (including the reabsorption of the ova into the body).
This phylum contains representatives of all the animals with a mouth. chordata is divided into two parts: notochord phylum, which includes all mammals with a canine or elk-type mouth (including humans); and chordophor physico-chemical phylum, which includes all animals with a bony mouth (including humans). Other chordata representatives are amphibians and vertebrates.
Chordata has four types of characters
This phylum chordata has four types of characters: primary, secondary, placenta, and metatarsus. Each character has specific traits that distinguish it from other members of its class. For example, the primary character has only two distinct traits, whereas all members of this phylum have six. Each trait is also related to the position of the body appendages (the metatarsus being at the front, and the craniates being in rear). The characteristics of each character are therefore independent, although they are correlated (if present) to one another. As a result, all chordata animals have a well-developed set of characteristics shared by all members of the phylum chordata.
Divided into two subphyla
This phylum chordata is further divided into two subphyla. The first subphylum, chordatae, comprises freshwater and saltwater fishes. The second subphylum, chordata and, comprises terrestrial and marine animals. Subclasses are further divided into three general categories, each denoting a particular grouping of chordata: primordial, basal, and postulated.
