The anemone fish Amphiprion clarkii (Bennett) lives unharmed among the tentacles of sea anemones following acclimation. What occurs during this process is unknown; however, two hypotheses have been formulated recently. One suggests that the fish coats itself with anemone mucus to mask its chemical stimulus for cnida discharge. The second suggests that the fish is protected by some alteration in its own mucous coating. In order to test these alternative hypotheses, a surrogate anemone was constructed and an Amphiprion allowed to associate with it prior to being placed with a real anemone. If the subsequent acclimation times to a real anemone are reduced significantly after exposure to the surrogate anemone, one would conclude that the fish does not need to coat itself with anemone mucus to become protected. After association with a surrogate anemone, it was found that the acclimation times of isolated A. clarkii to the sea anemone Macrodactyla doreensis (Quoy & Gaimard) decreased seven-fold. These results support the hypothesis that the fish is responsible for manufacturing its own protection from sea anemones, presumably by independently altering its own mucous coat during acclimation. |
