Definition

"Chordate" refers to an animal belonging to the phylum Chordata, characterized by having a notochord (a flexible rod-like structure) at some stage of development. This phylum includes vertebrates (animals with backbones) like humans, fish, birds, and reptiles. It's a broad category encompassing a huge range of animals. Think of it as the family tree that includes anything with a spinal cord or related structure. It is very inclusive.

Etymology

The word "chordate" comes from "chorda," the New Latin form of the Greek word "chorde," meaning "string" or "cord." This refers to the notochord, a defining feature of chordates. The suffix "-ate" indicates belonging to or possessing. Thus, "chordate" describes animals that possess a notochord at some point in their development.
