Describing organisms that grow, live, or burrow in sandy environments.
The arenicolous species of worms thrive in coastal sand dunes.
Arenicolous is formed from "arena" (from Latin "arena", meaning sand) and "-colous" (from Latin "colere", meaning to inhabit or dwell). The word describes organisms that inhabit sandy environments.
Think of 'arena' meaning sand and '-colous' meaning to dwell — this helps you remember that 'arenicolous' refers to creatures that live in sandy places.
