Root Explanation
Urochordate is formed from "uro-" (from Greek "oura", meaning tail) and "chordate" (from Latin "chordatus", meaning having a cord or string). The term refers to a group of animals that have a notochord (a flexible rod-like structure) during their larval stage, which is often associated with a tail.
Memory Tip
Think of 'uro-' meaning 'tail' and 'chordate' referring to having a 'cord' — this helps you remember that urochordates are animals that have a tail and a notochord during their early development.
