大鲵属两栖纲隐鳃鲵科,俗称娃娃鱼,是现存有尾两栖类中体形最大的一种,身长可达1米以上。多年来由于大鲵肉质鲜嫩,遭到人为滥捕,加之自然环境的破坏,其野外生存状况不容乐观,因此被国家列为二级保护动物,我国濒危动物红皮书和国际自然及自然资源保护联盟(IUCN)都将大鲵定为极危种。为了了解大鲵的生存状况,我们开展了一次全国范围的大鲵生境和野生数量调查。
Euphorbia is a family of amphibians, commonly known as giant salamanders. It is the largest species of amphibians in existence and can grow to more than 1 meter in length. Over the years, due to the fresh and tender meat of Dagu, it has been overfished by humans and destroyed by the natural environment. Its wild survival conditions are not optimistic. Therefore, the country has been listed as a second-class protected animal, the Red Book of Endangered Animals and the International Union for Conservation of Nature and Natural Resources (IUCN). ) All will be designated as extremely endangered species. In order to understand the status of Amnesty, we conducted a nationwide survey on the habitat and wild population.
