Chordate
Chordate explained in an easy to understand way:


Imagine you're moving into a new apartment and need to figure out which basic furniture pieces you'll need to feel settled. This situation is akin to how a chordate develops its essential features at some point in its life, like having a tail, nerve cord, notochord, and throat slits. Just as essential furniture pieces such as a bed, table, and chair are fundamental to making a space functional and comfortable, these anatomical features are the foundational elements that define a chordate, providing structure and function at some stage of its life.
