Is lancelet living or nonliving?
A lancelet is a living organism. It is a type of marine invertebrate with a simple body structure, similar to that of a fish. Lancelets are considered living organisms because they exhibit characteristics of life such as growth, reproduction, and response to stimuli.
How does gas exchange occur in the lancelet?
Gas exchange in lancelets occurs primarily through their skin and gills. As water flows over the gill slits, oxygen diffuses from the water into the lancelet's blood, while carbon dioxide diffuses from the blood into the water. This process is facilitated by the lancelet's position in the water and its constant movement, which helps maintain a flow of water over the respiratory surfaces. Overall, the thin-walled gills and skin provide a large surface area for efficient gas exchange.
The lancelet is a member of subphylum?
The lancelet belongs to the subphylum Cephalochordata within the phylum Chordata. They are small, fish-like marine organisms that exhibit characteristics of chordates, such as a notochord and a dorsal nerve cord.
Give an example of a lancelets?

What is amphioxus?
An amphioxus is a lancelet, particularly of the genus Branchiostoma.
What is an amphioxus?
An amphioxus is a lancelet, particularly of the genus Branchiostoma.
How does a lancelet obtain food?
The Lancelet is a filter feeder, so it will open its mouth - which has up to 100 or so gill slits - and as water passes through the mouth and gills, sticky mucus will catch and hold food particles, and after water has passed through, the Lancelet will swallow the mucus, and ta da! It has food.
Is a lancelet an invertebrate?
No. No felines/mammals/animals are invertebrates either.
