Barnacles adhering to the shells of sea turtles and whales to secure transportation to more favorable locations illustrate an instance of:
Show answer Hide answer
Answer: C. Commensalism
Explanation
Barnacles riding on whales and sea turtles for transport without harming the host exhibit commensalism. The barnacles gain mobility and access to feeding currents while the host remains unaffected. This ecological interaction provides benefits to one species without imposing costs on the other. Commensalism represents a type of symbiotic relationship between two different biological species. Marine organisms often utilize larger mobile animals as substrates for dispersal and survival. Host animals experience no physiological detriment or advantage from the attached barnacles.
Marine biologists study commensal relationships to understand complex ocean food webs and transport. Conservationists monitor marine mammal health, noting external symbionts during population surveys. Ecological field studies document diverse commensal associations across marine and terrestrial habitats. Lichen represents a mutualistic association between fungi and algae rather than barnacles. Mutualism requires both participating species to receive positive benefits from the interaction. Mycorrhiza describes symbiotic associations uniting plant roots with specialized soil fungi.
