The adult forms of both tunicates and lancelets are in face sessile creatures, as they are extremely docile and they spend most of their time either asleep or on the prowl for food, but never living food.
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.

The scientific name for tunicates is Phylum Chordata, Subphylum Tunicata.
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.
