2023年，上海启动了首次全市生物多样性本底调查。最近，科研人员在崇明区发现了令人振奋的成果。他们找到了三个在中国和上海从未记录过的新物种。

In 2023, Shanghai started its first full survey of local biodiversity. These days, scientists found exciting results in Chongming District. They discovered three new species for China and Shanghai.

第一个新物种名为类奇异布纹藻（拉丁学名：Surirella paranavis）。这是一种硅藻类生物。该藻类此前从未在中国被发现过。它生活在微咸水域，对环境变化非常敏感。藻体呈S形，表面布满细密纹路。

One new species is called Surirella paranavis. It is a type of algae (藻). This algae was never recorded in China before. It lives in slightly salty water and is very sensitive to environmental changes. Its body is S-shaped and covered with tiny lines.

同时发现的还有两种新摇蚊。它们的学名是直脉矮突摇蚊（Nanocladius rectinervis）和小型棒脉摇蚊（Corynoneura parvula）。这两种摇蚊都是上海的新记录种。摇蚊外形似蚊子但对人无害。它们的口器已经退化，不会叮咬。摇蚊幼虫多栖息在淤泥中，以腐烂植物和细菌为食。它们能分解废物，改善水质。

Two new midge (摇蚊) species were also found. They are Nanocladius rectinervis and Corynoneura parvula. These midges are new to Shanghai. Midges look like mosquitoes but are harmless. Their mouths cannot bite. Most midge larvae (幼虫) live in mud and eat dead plants or bacteria. They help break down waste and improve water quality.

去年，调查团队在崇明岛检测了46处水域。研究对象包括大型湖泊、村镇河道，甚至延伸至江苏省的部分河流。科学家们采集河底淤泥样本，使用特制浮游生物网捕捉微小生物。

Last year, the survey team checked 46 water areas in Chongming. They studied big lakes, small rivers, and even some rivers in Jiangsu Province. Scientists collected mud samples and used special nets to catch tiny creatures.

这些发现证明崇明水域生态系统丰富而复杂。有些物种可能已在此生存多年却未被察觉。进一步研究将帮助我们理解它们出现的原因。

These discoveries show Chongming’s water ecosystems are rich and complex. Some species might have lived here for years without being noticed. More studies will help us understand why they appeared here.
