As it stands, the answer is no, but, the hagfish status is still a little up for debate because it seems that they MAY have once had a vertebrate but then lost it through further specialization. They are the only animal to have a skull without a vertebrate.
Also, the hagfish's "skeleton" is not bone, but a softer, but still stiff, substance such as cartilage but not cartilage.

∙ 11y agoNo, hagfish are not invertebrates, they are chordates.
Chordates fall between invertebrates and vertebrates on the evolutionary ladder and, as such, they are the predecessors of vertebrates. Instead of having a backbone running along their bodies they have a stiffened rod of gristle. This is an early form of spine and is what enables hagfish to be so flexible .
