Lower chordates refer to a group of simple, marine invertebrate animals that belong to the phylum Chordata but do not possess a backbone or vertebral column. Examples of lower chordates include tunicates, lancelets, and hagfish. They are considered primitive chordates with some characteristics of vertebrates.
Locomotion in chordates refers to the movement of the body from one place to another. In chordates, locomotion can be achieved through various means, such as swimming, walking, crawling, or flying, depending on the specific characteristics of the organism and its environment.
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.
Lancelets, also known as amphioxus, are chordates that exhibit characteristics such as a notochord, dorsal hollow nerve cord, pharyngeal slits, and a post-anal tail. These features are present at some stage in their life cycle, distinguishing them as chordates.
Animals that have the four basic characteristics of chordates (dorsal hollow nerve cord, notochord, post-anal tail, pharyngeal slits) plus a vertebral column are known as vertebrates. Examples include mammals, birds, reptiles, amphibians, and fish.

They don't have a backbone and have all the characteristics of a chordate.

The presence of a notochord at some point in the organism's development is one of the characteristics that distinguishes chordates from other phyla. Without it, I'm not sure if the organism would be considered a chordate.
a hollow nerve cord, a notochord, pharyngeal pouches, and a postanal tail
All chordates will have (in some stage of their life) adorsal, hollow nerve corda flexible, rodlike, internal supporting structure called a notochordpaired gill slits in the throat region
The following are characteristics of Gregorio chants except:

all vertebrates are chordates because vertebrates are the sub- group of phylum chordates and also it follow one of the important feature of the chordates i.e. presence of notochord whereas all chordates are not vertebrates because some chordates are cephalochordates, urochordates.
There isn't a "popular name" for them. The most familiar chordates are the vertebrates, but not all chordates are vertebrates (tunicates, for example, are chordates).
