* Lichens: These are a symbiotic relationship between fungi and algae. They can often be seen as colorful patches on rocks and are a very common sight in caves.
* Mosses: These are small, non-vascular plants that can thrive in damp, shady environments, making caves a perfect habitat.
* Algae: Some types of algae can grow in dimly lit cave environments, especially near water sources.
* Biofilm: This is a thin layer of microorganisms, including bacteria, fungi, and algae, that can grow on surfaces in caves.
* Cave formations: These are not living organisms but can appear to grow on rocks. Examples include stalactites, stalagmites, and flowstone.
To determine the specific "stuff" growing on rocks in a cave, it's important to consider the cave's environment, the location, and the appearance of the growth.
