当我看到一则有关萤火虫与蜗牛的资料时,不由大吃一惊。资料上说,萤火虫竟然是肉食小甲虫,而它的食物就是蜗牛。看完全文,我才恍悟。原来,萤火虫的头顶有一对颚,弯拢来就成为一把钩子,钩子上有一条沟槽,那东西细小得像一根头发,很尖利。萤火虫捉蜗牛时,先用颚在蜗牛的肉体上轻? When I saw a piece of information about fireflies and snails, I was surprised. According to the data, the firefly is actually a meaty beetle and its food is a snail. To see the full text, I realized. It turned out that there was a pair of crickets on the top of the fireflies, which became a hook when they were bent. There was a groove in the hook. It was a small thing like a hair. It was sharp. When a firefly catches a snail, first lightly on the body of the snail.
