Tunicates and lancelets are invertebrates, while the other chordates are vertebrates.
During their embryonic stage they have a flexible cord that supports their bodies which disappears in the adult stage. Some of these develop bones surrounding the cord in the adult stage rather than have it disappear.
Tunicates and lancelets represent the two groups of jawless fish. All other species of jawless fish have gone extinct.
They are both filter feeders, don't have a backbone, have a notochord at some part of their life, and are in the phylum Chordata.
Lancelets have a definite head region and mouth, unlike tunicates.

What Tunicates and lancelets are two subphyla of animals classified as what?
chordates
How do tunicates and lancelets get their food?
They're filter feeders
Do tunicates and lanceletes have back bones?
No, tunicates and lancelets do not have backbones. They are invertebrates, meaning they do not possess a true backbone or vertebral column. Instead, they are part of the phylum Chordata, which includes vertebrates but also some simpler, spineless animals.
Are The adult forms of both tunicates and lancelets sessile?
The adult forms of both tunicates and lancelets are in face sessile creatures, as they are extremely docile and they spend most of their time either asleep or on the prowl for food, but never living food.
Is a tunicates an invertebrate?
Yes. So are lancelets. Both are invertebrates under phylum Chordata.
What is the difference between hagfish and lancelets?
bony jaws
What are some examples of non vertebrate chorodates?
Non-vertebrate chordates are those animals that have a notochord but no true backbone. There are two groups known as the tunicates and lancelets. Tunicates include sea squirts and salps. Lancelets are a group of burrowing filter feeders that live on the ocean floor.
Tunocates and lancelets are two subphyla of animals classified as what?
Tunicates and lancelets are two subphyla of animals that are classified as Chordata. This means that they have dorsal nerve cords as well as notochords.
What classifications are tunicates and lanceletes?
Tunicates and lancelets represent the two groups of jawless fish. All other species of jawless fish have gone extinct.
What are the three structures that all chrdates have in common?
Urochordata, represented by tunicates; Cephalochordata, represented by lancelets; and Craniata, which includes Vertebrata.
What kind of skeleton does a jawless fish have?
Agnathans are the jawless fish. They are usually fairly small (a few centimeters in length.) They consist of lancelets and tunicates. They have a notochord which is like a backbone, but it is more flexible than bone. Tunicates are enveloped by a tough tunic around their bodies. Other than that, they have no other bones.
What are the examples of protochordata?
Examples of Protochordata include Lancelets (Cephalochordata) and Tunicates (Urochordata). These organisms are marine chordates that exhibit characteristics of both invertebrates and vertebrates.
