Golden Toad 金蟾蜍
The brightly colored Golden toad hasn’t been seen since 1989
Once abundant in the cloud forests of Costa Rica, the golden toad came to a sudden extinction in the 1980s, after its habitat was drastically altered due to climate change. No other amphibians are known to display the toad’s distinct color, which was described by its discoverer, Jay Savage, as “Day-Glo orange.” The toads’ skin was shiny and bright too, which only furthered the illusion that it had been dipped in paint. Only male toads had such bright coloring; females were, in fact, mostly black with a few orange spots.
Golden toads were seen frequently in the cloud forests after their discovery in 1966. But in the 1980s, they became less common. Since 1989, no one has seen a Golden Toad. For a long time people hoped the toads were burrowed underground, waiting for conditions to improve. But after no sightings were seen for years, the toad was placed on the extinct species list in 2004.
中文背景：
金蟾蜍，又称环眼蟾蜍，美洲蟾蜍的一种，曾大量存在于哥斯达黎加蒙特维多云雾森林（Monteverde Cloud Forest Reserve，现已为自然保护区）中一片狭小的热带雨林地带，其雄性个体全身呈金黄色，因此被称作金蟾蜍。金蟾蜍1966年由爬虫学者杰伊·萨维奇（Jay Savage）发现并正式命名，1989年以后，金蟾蜍再没有被发现。至2006年，金蟾蜍在世界自然保护联盟濒危物种红色名录中的保护状况为绝灭，由于全世界范围内两栖动物数量不断下减，金蟾蜍绝灭的实例也被许多相关学者研究证实，一般认为，造成金蟾蜍绝灭的主要原因为全球变暖和环境污染.
