What Are the Underwater Bacterial Colonies Called?

Underwater bacterial colonies are commonly referred to as biofilms. These biofilms consist of communities of microorganisms, primarily bacteria, that adhere to underwater surfaces, such as rocks and sediments, and are usually embedded in a protective extracellular matrix.

Biofilms are crucial for various ecological processes in aquatic environments. They play a significant role in nutrient cycling, decomposing organic materials, and serving as a food source for other aquatic organisms. The formation of biofilms is a natural response of bacteria to enhance their survival in challenging underwater conditions, allowing them to stick to surfaces and form protective layers that shield them from environmental stressors.
