What is a Amphioxus Immature?

Amphioxus, also known as lancelets, are small, marine invertebrates that belong to the subphylum Cephalochordata. An immature amphioxus refers to the early developmental stages of these organisms, which exhibit key characteristics such as a notochord, dorsal nerve cord, and pharyngeal slits. These features are crucial for understanding the evolutionary link between invertebrates and vertebrates. Immature amphioxus play a significant role in developmental Biology and evolutionary studies.
