浙江高中生助力发现新型蛇类

浙江省一名17岁高中生胡嘉豪在括苍山进行了超过40个夜晚的实地观察,帮助发现了新型蛇类Achalinus mirabilis。这一发现是20世纪以来浙江省首个以本地为模式产地的全新爬行动物物种。研究人员称赞胡嘉豪提供了关键标本,推动了科学鉴定。

故事始于2024年10月18日,浙江省林业资源监测中心调查专家周家俊和当地生物爱好者陈浩军在括苍山勘测时,发现了一条不完整的蛇类遗骸。这条蛇细长,长约20-30厘米,身体呈棕色至深棕色,与常见物种不同。他们凭借专业经验,认识到其独特性。

高中生胡嘉豪从小热爱观察野生动物,通过在线平台联系上周家俊,后者以“周雨霏”用户名在网上科普。2025年暑假,胡嘉豪开始在括苍山搜寻蛇类。他每天完成学业后,携带专业摄影装备和防护设备,往返近100公里上山搜索。最初,他遵循传统观点,在雨后搜寻,但未果。随后,他调整策略,转而在晴朗夜晚进行观察。

突破发生在2025年8月17日晚,胡嘉豪下山时,一条细长的蛇突然从路边滑过。他迅速靠近观察,正是目标物种。这条成年雌蛇长逾30厘米,身体棕色,腹面浅棕,与先前遗骸特征吻合。它后来成为该物种正式描述的模式标本。

随后两个月,胡嘉豪继续勘测,在同一区域又发现两条活蛇和两条路死标本,总计五份标本。这些标本经处理后,送至大学和研究机构进行分子测序和形态分析,为新物种鉴定提供了关键证据。

新物种正式命名为括苍山锦蛇(Achalinus mirabilis),其CO1基因与最近亲种的差异为9.5%-10.9%。这一发现丰富了浙江省的生物多样性,并凸显了公民科学在科研中的潜力。研究结果于3月初发表于国际期刊《Zoosystematics and Evolution》。

项目负责人徐金安表示,胡嘉豪是鉴定这一新物种的“不可或缺的关键力量”,其提供的标本填补了研究中最关键的空白。

Researchers have unearthed a remarkable fossil site in southern China that preserves a 512-million-year-old marine ecosystem from the Cambrian period. The find, known as the Huayuan biota, offers insights into life after the Sinsk extinction event around 513.5 million years ago. It includes thousands of fossils, many previously unknown to science.

Researchers in China have discovered the fossilized remains of a juvenile iguanodontian dinosaur from 125 million years ago, featuring exceptionally preserved skin and unique hollow spikes. This new species, named Haolong dongi, represents the first documented case of such structures in dinosaurs. The find challenges previous understandings of dinosaur anatomy.

More than 700 fossils from the Jiangchuan Biota in Yunnan Province, southwest China, dating 554-539 million years ago in the late Ediacaran, include early relatives of starfish, acorn worms, deuterostomes, and other bilaterians. Led by Dr. Gaorong Li of Yunnan University, the discovery—after nearly a decade of fieldwork—challenges the suddenness of the Cambrian explosion by showing diverse animal communities predated it. The results, published in Science (DOI: 10.1126/science.adu2291), feature exceptionally preserved carbonaceous films revealing fine details like digestive systems.

An abandoned 85kg alligator snapping turtle found eating fish in a Hong Kong pond has prompted animal rights activists to demand a list of approved pets and tougher penalties for releasing animals into the wild. Experts say the discovery highlights the city's lag in biosecurity measures. The turtle, now named Yoshi, has been transferred to a community education base.
