Lancelets inhabit shallow marine waters. They are filter feeders that live in all the oceans in both cool and warm water.

Do tunicates and lanceletes have back bones?

No. They are both chordates, which means during embryonic development they have a notochord, the same as vertebrates. This does not persist in tunicates, but it does in lancelets (adults still have a notochord). Neither tunicates or lancelets have a backbone.


How do lancelet's obtain oxygen?

Lancelets obtain oxygen through a process called diffusion. They do not have specialized respiratory organs; instead, oxygen diffuses across their thin body walls and into their bloodstream from the water around them. This is made possible by their simple body structure and the high surface area-to-volume ratio of their bodies.


Do lancelets have a backbone?

No, lancelets do not have a backbone. They are small, fish-like marine invertebrates that belong to the subphylum Cephalochordata and possess a notochord instead of a true backbone.


Do lancelets have pharyngeal pouches?

Yes, lancelets do have pharyngeal pouches. These pouches are openings in the pharynx that are important for filter feeding and gas exchange in these small marine animals.


How do sea squirts and lancelets protect themselves?

sea squirts protect themselves by squirting out a jet of water, hence the name, and they also have a tunic which is a layer of tissue covering them that can be thick and tough or thin and translucent, which protects them from predators. Lancelets spend most of their lives buried in the sand with only their heads sticking out, and have a hood that covers the mouth and sensory tentacles surrounding it thus protecting their bodies from predators.

What is is the difference between tunicates and lancelets?

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.
