Yes. So are lancelets. Both are invertebrates under phylum Chordata.
Tunicates, (Sea squirts, Sea tulips) should adequately meet your desire for strange!
No, the phylum Chordata includes both vertebrate and invertebrate animals. Vertebrates are a subphylum within Chordata and have a backbone or spinal column, whereas invertebrate chordates, like tunicates and lancelets, lack a backbone.
Phylum Chordata simply consists of all animals that, at least in their embryonic phase, have a structure called the notochord. In the vertebrates, the notochord develops into the vertebrae, i.e. the backbone. Some primitive chordates, though, including the tunicates, lancelets, and hagfish, do not ever develop vertebrae, although they have/have had a notochord. Hence, Subphyla Urochordata and Cephalochordata, and Class Myxini are invertebrate chordates.
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.
Tunicates are invertebrate marine animals. These animals have very simplistic or lack an excretory systems and must eliminate nitrogenous waste through the diffusion of ammonia through their tissues. A sea squirt is a tunicate.

Because they have no back bone
Tunicates are invertebrates.
