What animals are chordates but not vertebrates?
Non-vertebrate chordates: Cephalochordata (lancelets), Urochordata (Tunicates), and Myxini (hagfishes) These groups are the chordates which do not possess vertebrae. Many are hermaphroditic, sessile or buried within the sand of aquatic environments, and hatch from eggs within the parent’s body.
What Chordata is not vertebrate?
Amphioxus also known as lancelet is a fish-like marine chordate. Unlike vertebrates, the dorsal nerve cord is not protected by bone but by a simpler notochord made up of a cylinder of cells that are closely packed to form a toughened rod.
Which are examples of non vertebral chordates?
The tunicates and the lancelets, of the subphyla Urochordata and Cephalochordata respectively, are the two main nonvertebrate chordates.
What are 5 examples of chordates?
Pandas, crows, sharks, salamanders, alligators, sea squirts, and many others are examples of chordates. So, in essence, to answer the question, amphibians, reptiles, and mammals comprise which group? — the answer is simply they belong to the phylum Chordata.

Are all chordates also vertebrates?
The Chordata is the animal phylum with which everyone is most intimately familiar, since it includes humans and other vertebrates. However, not all chordates are vertebrates.
Why are all chordates not vertebrates?
The members of Vertebrata possess notochord during embryonic development. Thus, all vertebrates are chordates. However, the notochord gets replaced by a cartilaginous or bony vertebral column in the adult. Thus, all chordates are not vertebrates.
