The scientific name for tunicates is Phylum Chordata, Subphylum Tunicata.
The common name for subphylum Urochordata is tunicates or sea squirts. These marine animals are characterized by their cylindrical bodies encased in a tough tunic made of cellulose.
Tunicates are part of the phylum Chordata, and there are as many of 2,150 species of them. Sea stars, flatworms, and snails are some of the predators of tunicates.

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).
chordates
No. They are both chordates, which means during embryonic development they have a notochord, the same as vertebrates. This does not persist in tunicates, but it does in lancelets (adults still have a notochord). Neither tunicates or lancelets have a backbone.
Because they have no back bone
Tunicates are invertebrates.
