    Symbiotic Relationships

    • Mutualism: benefits both host and symbiont.
      • Example: Anemone and the anemone fish; fish cleans and feeds anemone, stays with anemone for protection – fish can’t be stung (clown fish) (Figure 14.29)
    • Commensalisms: no effect on host, benefits symbiont.
      • Example: Shark and pilot fish (pilot fish eats leftovers). Or barnacles attached to a humpback whale (Figure 14.30).
    • Parasitism: Harms host, benefits symbiont.
      • Examples: Parasites in tuna. Humans catching and eating tuna (with parasites).
