Barnacles on whales don't exactly enjoy free rides; rather, they attach themselves for survival. Being on a whale helps barnacles get closer to nutrient-rich waters, facilitating better filter feeding. This relationship is known as commensalism: barnacles benefit while the whale remains largely unaffected.

  1. What is commensalism in marine biology? Commensalism is a type of symbiotic relationship where one organism benefits while the other is neither helped nor harmed.
  2. Why do barnacles attach to whales? Barnacles attach to whales to access nutrient-rich waters, enhancing their ability to filter feed effectively.
  3. Do barnacles harm whales? No, barnacles do not harm whales; instead, they benefit from riding on them, while whales are largely unaffected.
  4. What other animals form commensal relationships? Many animals, including certain fish and birds, exhibit commensal relationships with various marine and land species.
