A team of amateur cave explorers and arachnologists has found a new family of spiders in caves and old-growth redwood forests in Oregon and California, U.S. researchers said Friday.
Entomologists at the California Academy of Sciences said the spider, named Trogloaptor -- or "cave robber" -- for its lethal front claws, had such unique evolutionary features that it represented not just a new genus or species, but also a new family of spiders.
The study, published in the journal ZooKeys, noted that finding a new, previously unknown family was rare, even for species-rich insects and arachnids.
Trogloraptor hangs beneath rudimentary webs spun below cave ceilings. It measures about 1.6 inches (four centimeters) wide when its legs are extended.
Trogloaptor真的是新品種蜘蛛嗎？還是以前沒有發現而已？ 該不會是外星人把某蜘蛛抓去研究，OOXX一頓以後，就變成這種新的蜘蛛？ 萬一某老美被這種新品種蜘蛛咬到，搞不好會變成蜘蛛人！
