What is the body symmetry of Chordata?
Bilateral symmetry
Chordates are bilaterally symmetrical, which means there is a line of symmetry that divides their body into halves that are roughly mirror images of each other. Bilateral symmetry is not unique to chordates.
Do chordates have body segments?
The arthropods, annelids, and chordates are universally considered segmented.

Chordate/Lower classifications
What type of body plan do chordates have?
Chordates share a common, generalized body plan and can be diagnosed by four features shared by members of all the major groups: a notochord, pharyngeal slits, a hollow dorsal nerve tube, and a postanal tail (an extension of the body posterior to the anus).
What type of body cavity do chordates have?
All chordates are coelomates, and have a fluid-filled body cavity called a coelom with a complete lining called peritoneum derived from mesoderm (see Brusca and Brusca).
What phylum is the body segmented?
Segmentation in biology is the division of some animal and plant body plans into a series of repetitive segments. This article focuses on the segmentation of animal body plans, specifically using the examples of the taxa Arthropoda, Chordata, and Annelida.
What animals are phylum Chordata?
ChordateVertebrate / Phylum
Which are considered a blueprint of the phylum Chordata?
Answer. Answer: The lancelets are also called cephalochordates,because the notochord extends from near the tip of the tail to well into the anterior of the body. Because they do not have the braincase, or cranium, of a vertebrate, lancelets are often called acraniates.
What are the general characteristics that are found in the body plan of all chordates?
The five characteristic features of chordates present during some time of their life cycles are a notochord, a dorsal hollow tubular nerve cord, pharyngeal slits, endostyle/thyroid gland, and a post-anal tail.
Do humans have pharyngeal slits?
All chordates possess a tail and pharyngeal slits at some point in their lives, and humans are no exception. Early on in human development, the embryo has both a tail and pharyngeal slits, both of which are lost during the course of development.
Do chordates have backbones?
The phylum Chordata consists of animals with a flexible rod supporting their dorsal or back sides. The phylum name derives from the Greek root word chord- meaning string. Most species within the phylum Chordata are vertebrates, or animals with backbones (subphylum Vertebrata).
What do all chordates have in common?
1: Defining characteristics of chordates: 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.
What is a trunk body?
The main part of the body that contains the chest, abdomen, pelvis, and back. Most of the body’s organs and the backbone are found in the trunk. Also called torso.
