善於在敵人面前裝死的螃蟹,竟因長期被船隻的噪音嚇到而忘了這本領!研究發現,當螃蟹在嘈雜的環境下生活,會變得遲鈍。除了忘記裝死、減慢逃走速度,更會減少覓食。這對牠們的成長和生存造成很大的影響,最終影響到牠們的數目和整個生態系統!
crabs are naturally talented to “play-dead” when there are predators, but many are losing this behavior after living in shores with ship noises! study found that crabs that live in a noisy environment could make them forget to “play-dead” and slower their retreat speed; it would end up with less effective feeding as it takes them more time for foraging . all of these would affect the crabs’ growth and survival, as well as their populations and the whole ecosystems!
