Name the interaction between a whale and the barnacles growing on its back.

The relationship between a whale and the barnacles that attach to its back is known as commensalism. In this type of interaction, one species benefits while the other is neither helped nor harmed.

Understanding Commensalism

In this case, the barnacles gain a place to live and access to nutrient-rich waters as the whale swims. The whale, on the other hand, does not experience any significant impact from the barnacles.

Key Points About This Interaction

• Benefit for Barnacles: They receive food and a stable habitat.
• No Harm to Whales: The presence of barnacles does not affect the whale's health or mobility.
• Common in Nature: Commensalism is a widespread interaction seen in various ecosystems.

This fascinating relationship highlights the complexity of marine ecosystems and how different species can coexist.
