摘要在实验室条件下研究了寄居蟹Pagurus filholi的交配行为，并阐明了其交配顺序。交配顺序不同，这取决于男性对女性的大小比例。在交配前，相对于潜在的雌性配偶，体型较大的雄性倾向于进行交配前的守卫行为，即，用它们的螯足抓住雌性的壳的边缘，比较小的雄性更频繁。另一方面，较小的男性相对于女性似乎插入他们的螯足，并试图通过拉女性的壳没有执行precopulatory配偶守卫行为交配。这些不同的行为可能是有条件的策略，取决于男性/女性的大小比例。
ABSTRACT We studied the mating behavior and clarified the mating sequences of the hermit crab Pagurus filholi under laboratory conditions. The mating sequences differed, depending on the male to female size ratio. Before copulation, larger males relative to potential female mates tended to perform precopulatory guarding behavior, i.e., grasping the rim of the shell of the female with their chelipeds, more frequently than smaller males. On the other hand, smaller males relative to the females appeared to insert their chelipeds and to attempt copulation by pulling the female out of the shell without performing precopulatory mate-guarding behavior. These different behaviors may be conditional strategies that depend on the male/female size ratio.
