In addition to having a post-anal tail, a notochord, and a dorsal, hollow nerve cord (among other traits), chordates also have two pharyngeal slits. These are the four most obvious characteristics that separate chordates from animals in all other phyla (also called gill slits).
Which of the following is a characteristic of all chordates quizlet?
Chordates are deuterostomes, which means they have four distinct features that occur at various points throughout the animal’s existence. In addition, there is a muscular postanal tail and a dorsal hollow nerve cord, which are all distinguishing hallmarks of the notochord.
Which of the following characteristics are not common to all chordates?
Non-chordate animals lack the notochord, pharyngeal gill slits, and post anal tail that are found in chordate animals.
Which is a shared characteristic of all chordates?
Four distinguishing characteristics are shared by all animals belonging to the phylum Chordata: a notochord, a dorsal hollow nerve cord, pharyngeal slits, and a post-anal tail.
Which of these is a characteristic feature of chordates during development?
Chordates have the following distinguishing characteristics: Chordates have four distinguishing characteristics that occur at various stages of development: a notochord, a dorsal hollow nerve cord, pharyngeal slits, and a post-anal tail (see illustration).
What are the four defining characteristics of Chordata?
“The notochord, a single dorsal tubular nerve cord, pharyngeal pouches, and a postanal propulsive tail are the four distinguishing traits that, taken together, distinguish chordates from all other phyla.
What are the four shared characteristics of all chordates quizlet?
Among the derived features of chordates are a notochord, pharyngeal clefts or slits, a dorsal, hollow nerve cord, and a muscular, post-anal tail. Chordates also have pharyngeal clefts or slits.
What are the difference between chordates and non chordates?
The most important distinction between chordates and non-chordates is that chordates have a spinal cord or backbone in their body structure, whereas non-chordates do not have a spinal cord or backbone in their body structure, which is known as a notochord.
Which of the following is not a distinctive character of non Chordata?
There is no post-anal tail present.
Which of the following is not present in all chordates?
There are several chordates that do not have a vertebral column. Unlike in chordates, where it is present throughout life in some protochordates, in vertebrates it is only present during the embryonic stage, and is replaced by a vertebral column during the adult stage of development (Backbone).
Which is characteristic of all mammals and only of mammals?
Warm-blooded mammals that have hair or fur, are born alive and feed their young with milk generated by the mother’s mammary glands, and have a more sophisticated brain than other animals have been discovered. 2.

What four unique characteristics do all chordates possess during some point in their development?
Chordates have four distinguishing characteristics that occur at various stages of development: a notochord, a dorsal hollow nerve cord, pharyngeal slits, and a post-anal tail (see illustration).
What are the 5 chordate characteristics?
At some time during their larval or maturity phases, all chordates exhibit five synapomorphies, or basic traits, that separate them from all other species. The notochord, dorsal hollow nerve cord, endostyle or thyroid, pharyngeal slits, and post-anal tail are the five synapomorphies that have been identified.
