Definition

The slow build-up of tiny living things, like bacteria and small animals, on surfaces in water, which can cause damage and make machines work less well.

Example

The ship's hull was covered in biofouling, making it less efficient in the water.

Conversation

Have you heard about biofouling in marine structures?

Yeah, it can really mess with their efficiency, right?

Exactly! It's surprising how it contributes to corrosion over time.

Totally, I didn't realize it was such a big issue until recently.

Synonyms & Antonyms

Root Explanation

Biofouling is formed from "bio-" (from Greek "bios", meaning life) and "fouling" (from Old French "fouler", meaning to trample or to soil). The term describes the process where living organisms accumulate on submerged surfaces, thus 'soiling' them with life forms.

Memory Tip

Think of 'life' ('bio-') accumulating and 'soiling' ('fouling') surfaces — that's what biofouling means.
