What are the charcterisics of a chordate?

Answer 1

At some point in their lives, a chordate will have a notochord, a nerve cord that runs down their back, and a slit in the throat area. The phylum name Chordata came from the notochord, a flexible rod that supports the back. They include fishes, amphibians, and reptiles.

(I got this answer from my science textbook)

Characteristic features of Chordata

1. The chordates are one of the most diverse and successful of all animal groups.

2. They are found in all regions of the world.

3. They have a skeletal rod called Notochord, lying on the dorsal side of the body.

4. There is a nerve cord that lies dorsally in the body, directly above the notochord.

5. There is presence of Pharyngeal Gill slits atleast at the embryonic stage.

6. Digestive system, Circulatory system and Nervous system are well developed.

7. Those animals in which the notochord is replaced by a series of vertebrae are called as Vertebrates.

8. Amphibia, Reptilia, Aves, and Mammalia are some of the classes of Phylum Chordata.
They have bilateral symmetry, are coelomates, complete digestive system, and live in marine, terrestrial, and freshwater.
All chordates have pharyngeal slits, which are openings that connect the inside of the throat to the outside of the neck, often used as gills. Their main feature, the notochord, a bundle of nerve fibers which connect the brain with the muscles and organs is present in all chordae's as well.
In chordates, four common features appear at some point during development: a notochord, a dorsal hollow nerve cord, pharyngeal slits, and a post-anal tail.

Answer 2

The most important characteristic shared by Chordates is the presence of a notochord (albeit many of them don't keep it for the whole of their lives). The other characteristics are: a dorsal nerve tube, pharyngeal slits and an endostyle.

Answer 3

At some stage in the chordates life cycle it shows:

• · a notochord - a long, stiff rod of cartilage that runs longitudinally through the animal between the nerve cord and digestive tract

• · a dorsal, tubular (hollow) nerve cord

• · pharyngeal slits - openings in the region of the digestive tract immediately behind the mouth (pharynx) that allow water to pass

• · a post-anal tail (in most other animals with a complete digestive tract, the anus is the posterior-most point of the body).

Answer 4

All Chordates have:

1) a notochord

2) pharyngeal slits

3) a postanal tail

4) a hollow dorsal nerve chord

Answer 5

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 pharangeal slits.

Answer 6

the oresence of a notochord defines whether an organism is a chordate....

Answer 7

All Chordates have:

1) a notochord

2) pharyngeal slits

3) a postanal tail

4) a hollow dorsal nerve chord

Answer 8

They are:

a. a dorsal, hollow nerve chord

b. a notochord

c. pharyngeal gill slits

d. and a post-anal tail

Answer 9

it as hollow nerve cord that lies dorsal to the noto chord. it also has pharyngeal pouches.
