Symbioses between hermit crabs and sea anemones will be studied to determine the interactions and adaptations that have evolved. Experiments will determine: 1) whether the numbers and locations of anemones on the gastropod shell affect the survival of hermit crabs subjected to predation. 2) whether altering the shell's center of gravity alters the placement of anemones by the hermit crabs. 3) whether hermit crabs will take anemones from another crab more often when a predator is present. 4) whether hermit crabs will select shells with anemones more often when a predator is present. 5) the chemosensory abilities of the hermit crabs towards various predators and the anemone. 6) whether the anemone is protected from starfish predation by being transported with the hermit crabs. Such protection would demonstrate that this association represents mutualism.

寄居蟹和海葵之间的共生关系 研究以确定相互作用和适应， 进化了 实验将确定：1）数字是否 海葵在腹足类贝壳上的位置会影响 寄居蟹在捕食下的生存 2)是否 改变炮弹的重心， 寄居蟹旁边的海葵 3)寄居蟹是否会 海葵从另一只螃蟹更经常当捕食者存在。 4)寄居蟹是否会选择有海葵的贝壳 通常是在捕食者出现的时候 5)化学感受能力 寄居蟹对各种捕食者和海葵的反应。 6)海葵是否能免受海星的捕食 与寄居蟹一起被运送。 这种保护将 证明了这种联系代表了互利共生。
