Abstract

Abstract: The behavior of hiding molted shells has not been documented in any crustacean. The White-spotted hermit crab (Dardanus megistos) inhabiting tropical coral reefs has a unique molt behavior in which it hides its outer, shed shells in the sand. Video cameras were used to capture the molting behavior. After molting, the crab folds the molted exoskeleton, pressing the cephalothorax with both forceps, and buries the shell with its walking legs, until it is no longer visible.

大型寄居蟹奇特的换壳行为

摘要:在任何甲壳类动物中，尚未发现隐藏蜕皮壳的行为。生活在热带珊瑚礁中的白斑寄居蟹(Dardanus megistos)有一种独特的换壳行为，它把外壳藏在沙子里。用摄像机记录了它们的换羽行为。脱壳后，蟹将脱壳的外骨骼折叠起来，用两只钳子压住头胸，用走路的腿把壳埋起来，直到看不见为止。
