Does a chordate have a pharyngeal pouch?

Yes, chordates possess pharyngeal pouches at some stage of their development. These structures are part of the embryonic development in vertebrates and can develop into various structures, such as gills in fish or structures in the throat region in mammals. In humans, for instance, they contribute to the formation of parts of the ear and throat. Thus, while the presence and function of pharyngeal pouches vary among different chordate species, they are a characteristic feature of this group.
