tunicate
I do not know to be honest, sorry.
Because it does not have a "back bone".
It is vertebrate Chordate.
No. A snake is a vertebrate.
No, it is an invertebrate or non-chordate
The body plan of an invertebrate Chordate is quite unique as it does not entail a backbone. It has a hollow dorsal nerve cord and post-anal tail among other crucial features.
The notochord of a vertebrate differs from that of an invertebrate because a vertebrates eventually turns into a back bone. Invertebrates just disappears.
They don't have a backbone and have all the characteristics of a chordate.
No, a narwhal isn't an invertebrate. Instead, it has a backbone. It belongs to the Chordate phylum, which has mostly vertebrate members. It also belongs to the class of Mammals, which all have backbones.

One example of an invertebrate chordate is the lancelet (Branchiostoma). Lancelets are small, fish-like marine organisms that possess a notochord, a dorsal nerve cord, and pharyngeal slits. They lack a true vertebral column but exhibit key characteristics of chordates.
a hydra as a polyp is not sessile but when it grows to be a hydra it is sessile
