Root Explanation

Amphioxus → It is formed from "amphi-" (meaning both or on both sides) and "oxus" (from Greek "oxus", meaning sharp or pointed). The word refers to an organism that has features on both sides, particularly in its body structure, resembling a fish.

Memory Tip

Think of 'both sides' ('amphi-') and 'sharp' ('oxus') to remember that amphioxus refers to a creature with features on both sides, like a pointed fish.
