Here's why:
* Chordates are a phylum of animals that share certain key features at some point in their development. These features include:
* Notochord: A flexible rod that supports the body.
* Dorsal hollow nerve cord: A tube of nerve tissue running along the back.
* Pharyngeal slits: Openings in the throat that are used for filter feeding in some species.
* Post-anal tail: A tail that extends beyond the anus.
* Wolves, being mammals, belong to the class Mammalia.
* Mammals are a group of vertebrates that are further classified within the phylum Chordata.
Therefore, the chordate for a wolf is Chordata.
