The 'clown' fish lives among the tentacles of sea anemone. What is this interaction between them called and why ?

Explanation

**Step-by-Step Solution:**

1. **Identify the Organisms and Their Interaction**: The clownfish and the sea anemone are two different species that interact with each other in their ecosystem.

2. **Define the Type of Interaction**: This interaction can be classified as either commensalism or mutualism.

3. **Explain Commensalism**: In commensalism, one organism benefits while the other is neither helped nor harmed. In this case, the clownfish benefits from living among the sea anemone's tentacles, as it gains protection from predators due to the anemone's stinging tentacles. The sea anemone, however, does not gain any benefit from the clownfish's presence.
