Mantis shrimp, colloquially known as the "smelly sea creature," feed on small shrimp. Since small shrimp used to be one of Matsu fishermen's main catches, the fishermen loathed mantis shrimp and threw away any that they inadvertently caught.
蝦蛄又名「海臭蟲」，以蝦米為食，過去馬祖漁業以捕蝦米為主，漁民因而對蝦蛄恨之入骨，凡捕捉到無不當場丟棄以免觸霉頭。
