HANGZHOU, Oct. 4 (Xinhua) -- Chinese researchers have discovered a new species of fish, Opsariichthys iridescens, in east China澳门六合彩, which features beautiful colors.

The research findings describe how the species is distinguished from congeners by morphological features, which have been validated through gene-based phylogenetic analysis.

想象一下，当你把一个暖手宝放在手臂上，温度刚刚好，既不冷也不热，是不是感觉特别舒服？但正是这种“刚刚好”的温度（45℃到60℃），因为不会触发我们的疼痛警报，反而让皮肤在不知不觉中受到了伤害。低温烫伤，就是这么悄无声息地发生了。

慢性疲劳综合征(CFS)是指没有器质性病变澳门六合彩，反复发作的，以极度疲劳为主的一种综合征。患者往往出现无力、疲劳、睡眠质量差、认知功能下降及一系列的躯体症状，比如以反复咽痒、肌肉痛、头痛、关节痛、抑郁、焦虑等为特征。

The discovery was published in a recent edition of the international academic journal Zookeys. The research was led by Yang Jinquan, a professor at Shanghai Ocean University, in collaboration with the Zhejiang Forest Resource Monitoring Center and other institutions.

The new species can be distinguished from its closely related species with a genetic divergence of over 14 percent, according to the research findings. The new species is found in the Qiantang and Oujiang River systems in Zhejiang Province and the tributaries of the lower Yangtze River adjacent to the Qiantang River.

Yang said that the discovery of several new species living in fast-flowing rivers or streams including Opsariichthys iridescens, indicates that the diversity of freshwater fish species in the region is still underestimated.

According to Yang, these stream fish species are food resources for waterfowl and other animal, contributing to the nutrient cycling and water purification of rivers.

Yang said protecting these fish species is essential to maintaining the balance of aquatic ecosystems澳门六合彩, which helps to maintain biodiversity and promote the sustainable development of ecotourism and fisheries.  ■
