FAQ
Frequently Asked Questions
No. Cephalochordates are invertebrate chordates. They are more primitive than fish and lack features like jaws, paired fins, and a true vertebral column.
The lancelet, particularly species in the genus Branchiostoma (formerly Amphioxus), is the classic example.
They are considered the closest living invertebrate relatives to vertebrates, making them a key model for understanding the evolutionary transition from invertebrates to vertebrates.
They have a simple nerve cord with a slight enlargement at the front end, but not a complex, differentiated brain like that of vertebrates.

Learning
Memory Aids
Mnemonic
Think: 'CEPHALO' (head) + 'CHORD' (spinal cord/notochord) + 'ATE' (having). It's a chordate where the notochord goes to the head.
Conceptual Metaphor
Often metaphorically described as a 'living fossil' or a 'window into vertebrate ancestry'.
