🔬 物种简介
射水鱼拥有罕见的捕猎技能——向水面上方的昆虫精确喷射水柱,将猎物击落水中。其眼睛能修正光线在水面折射造成的偏差,命中率极高。是自然界少数能利用工具(水)进行远距离攻击的动物之一。

Wikipedia
The archerfish or Toxotidae are a family of percomorph tropical fish known for their unique predation technique of "shooting down" land-based insects and other small prey with jets of water spit from their specialized mouths. The family is small, consisting of ten species in two genera, Toxotes and Protoxotes. Most archerfish live in freshwater streams, ponds and wetlands, but two or three species are euryhaline, inhabiting both fresh and brackish water habitats such as estuaries and mangroves. They can be found from India, Bangladesh and Sri Lanka, through Southeast Asia, to Melanesia and Northern Australia.
