any member of either of two invertebrate subphyla of the phylum Chordata: the Tunicata (sea squirts, salps, etc.) and the Cephalochordata (amphioxus). Like the remaining subphylum of the chordates, the Vertebrata, the protochordates have a hollow dorsal nerve cord, gill slits, and a stiff supporting rod, the notochord, the forerunner of the backbone. The protochordates differ chiefly from the vertebrates in not having a backbone. Recent protochordates are thought to have evolved from the same ancestral stock as that which gave rise to the vertebrates.

Are lancelets not true chordates?
They are actually true chordates, however they are some of the simplest chordates.
Why is a kangaroo classified in the phylum Chordata?
Most living chordates have backbones but all have notochords at some point in their development. In the case of the kangaroo, it had a notochord while an embryo.
Are chordates eukaryote?
Chordates are a group of animals which include vertebrates (animals having a spinal column), so yes, birds are chordates.
Is it true that classified ma be discussed only over secure equipment?
true
What are the unique features of chordates?
chordates have spinal cord and it separates it from the animals which do not have spinal cord
What are non-vertebrate chordates?
Cephalochordates e.g. Amphioxus ,; tunicates , acorn worms etc. are nonvertebrate chordates , they are collctively called protochordates .
Are lancelets not true chordates?

What should ascidians classified with?
chordates
Is hemichordata same as protochordata?
No, hemichordata and protochordata are not the same. Hemichordata is a phylum of marine deuterostome animals, while Protochordata is a subphylum of chordates that includes organisms like tunicates and lancelets. Both groups are primitive chordates but belong to different taxonomic classifications.
What Tunicates and lancelets are two subphyla of animals classified as what?
chordates
Why are birds and gorillas classified in the same phylum?
They both have a notochord, which qualifies them as chordates.
Which organism has a true body cavity?
chordates
What is a characteristic shared by all chordates the phylum in which humans are classified?
One characteristic shared by all chordates is the presence of a notochord, a flexible rod that provides structural support. Humans, being classified under the phylum Chordata, possess a notochord during their embryonic development that eventually develops into the spinal column.
What is the significance of Protochordates?
The name Protochordates literally means 'the first chordates.' The chordates include fish, amphibians, reptiles, birds and mammals. The protochordates fall into two broad groups or subphyla - the Urochordata and the Cephalochordata. Urochordata The urochordata includes the group known as the tunicates - animals whose free-swimming larvae have a notochord* and a nerve chord. The adults are sessile - that is to say they are anchored to one place on the Reef. CephalochordataCephalochordates, or lancelets, are fish-like animals that have a notochord and nerve chord along the entire length of their bodies and which persist all their lives. * A notochord is a an elongated cellular chord enclosed in a sheath, that forms the primitive skeleton of chordate embryos (including humans) and adult cephalochordates.
