Do pharyngeal slits disappear before birth in all chordates?
No, pharyngeal slits do not disappear before birth in all chordates. In some chordates, such as fish, these slits persist throughout their life and play a role in respiration and feeding. In other chordates, such as mammals, the pharyngeal slits do not persist through adulthood but are present during embryonic development.
What type of embryos have pharngeal slits?
All chordates embryos have pharngeal slits.
What types of embryos have pharyngeal slits?
all chordates
The three things all chordates have?
Chordates all possess a notochord (dorsal supporting rod), gill slits, and a dorsal nerve cord some time in their life cycles.
What distinguishes a chordates?
At some point in all chordates' lives, they have a notochord, a nerve chord, gill slits and a tail. Some chordates are more complex though.
What are the respiratory organs of chordates?

What do all choradates have?
all chordates have notochord, gill slits, postanal tail, and nerve chord.
What organisms have pharyngeal gill slits and a dorsal hollow nerve cord at some time in their development?
Organisms that have pharyngeal gill slits and a dorsal hollow nerve cord at some point in their development include chordates, such as fish, amphibians, reptiles, birds, and mammals. These features are key characteristics of chordates during their embryonic stages.
What are the four body parts of all chordates?
Notochord, Postanal Tail, Pharyngeal Slits, Dorsal hollow nerve cord
What is the common name for chordates?
Chordate is the common name for a very large group of animals (kingdom Animalia) that, at some stage in their life cycle, have something resembling a spinal chord or column, and gill slits. The phylum is called Chordata, and includes humans (we have gill slits in our fetal stage.
Are lancelets not true chordates?
Lancelets are considered true chordates because they possess a notochord, dorsal nerve cord, pharyngeal slits, and a post-anal tail at some stage in their life cycle, which are characteristic features of chordates. They are believed to represent an early evolutionary stage of the chordates.
What is the movement for chordates?
The movement for chordates is characterized by the presence of a notochord, dorsal nerve cord, pharyngeal slits, and a post-anal tail at some stage of their development. These characteristics are unique to chordates and help differentiate them from other animal groups.
