Root Explanation

Epifaunal → It is formed from "epi-" (meaning upon or above) and "fauna" (from Latin "fauna", meaning animal life). The word "epifaunal" refers to organisms that live on the surface of the sea floor or on other substrates, indicating their position above the substrate.

Memory Tip

Think of 'epi-' meaning 'upon' and 'fauna' referring to 'animal life' — this helps you remember that 'epifaunal' describes animals living on the surface.
