ScienceDaily (July 22,2004) — Scientists in San Diego have described the earth's smallest,lightest animal with a backbone.H.J.Walker of Scripps Institution of Oceanography at the University of California,San Diego,and William Watson of the Southwest Fisheries Science Center,National Marine Fisheries Service,in La Jolla have identified the miniscule "stout infantfish," a new species no longer than the width of a pencil.
世界上最大的蜘蛛是格莱斯捕鸟蛛,又称蜢蜘.生活在拉丁美洲圭亚那热带雨林中
根据我查到的英文资料：
The Goliath bird-eater Spider (also called the Goliath Birdeater)
It is native to the rain forest regions of northern South America.
所以英文译名应该是【Goliath Birdeater】或者【Goliath bird-eater Spider】
