Several introductions of damaging insects have been attacked successfully by further introductions of critters that eat them—though this has not worked so well for voracious introduced molluscs called giant African land snails.

通过进一步引入以它们为食小，成功地攻击了几种引入破坏性昆虫——尽管这对被称为巨型非洲陆生蜗牛贪婪引入软来说效果不佳。

Their journey from small, passive molluscs to sleek, voracious predators took hundreds of millions of years of trial and error -- from developing shells to survive, to finally learning to thrive without them.

In early fish-like vertebrates more than 500 million years ago; in a common ancestor of arthropods, such as insects, spiders and crustaceans, at around the same time; and then in the cephalopod molluscs around 300 million years ago.

在 5 亿多年前早期类鱼脊椎中；节肢共同祖先，例如昆虫、蜘蛛和甲壳类，大约同时出现；然后是头足类软大约 3 亿年前。

His undoing began when a committee of the Royal Society-a committee of which he happened to be chairman decided to award him its highest honor, the Royal Medal, for a paper he had written on an extinct mollusc called the belemnite.
