Root Explanation

**Mesozoan** → It is formed from "meso-" (from Greek *mesos*, meaning middle) and "zoan" (from Greek *zoon*, meaning animal). The word refers to a group of animals that are characterized by their middle position in the evolutionary scale, particularly in relation to other animal groups.

Memory Tip

Think of 'middle' ('meso-') and 'animal' ('zoon') to remember that 'mesozoan' refers to animals that occupy a middle position in the evolutionary hierarchy.
