高強度的紫外光、高溫高壓無氧氣，單憑字面來看已經感受到其強大的破壞力，究竟地球上還有沒有生物可以在這嚴峻的環境生存得到?472Please respect copyright.ＰＥＮＡＮＡSWCPvVJtP5

水熊蟲(Water Bears)，就是其中一種能夠活下來的生物。472Please respect copyright.ＰＥＮＡＮＡMD1B1rCXuS

（圖2）水熊蟲是約長0.5-1mm的小型動物，屬於緩步動物科，約有1300隻品種。472Please respect copyright.ＰＥＮＡＮＡ3KkEbGSDCn

牠們大多聚居在潮濕土壤及青苔裡頭，深海裡頭亦能找到牠們的蹤影，甚至在太空環境亦能生存得到，生命力非常頑強。472Please respect copyright.ＰＥＮＡＮＡmjuKCKeMFd

（圖3）最近有科學家發現（Fig1)，某品種對紫外光呈高抗性的水熊蟲品種，會在紫外光照射底下發出藍光。472Please respect copyright.ＰＥＮＡＮＡ8Q7jxUk2Ck

他們亦嘗試抽取水熊蟲水溶性的部份，發覺裡頭的色素能夠有效為其他低紫外光抗性的水熊蟲及其他蟲類抵擋紫外光帶來的殺傷力。472Please respect copyright.ＰＥＮＡＮＡlKqTaXThiK

除水熊蟲外，鸚鵡在紫外光下均會發出螢光，但會否為牠們帶來紫外線的抵抗力還是疑問。472Please respect copyright.ＰＥＮＡＮＡybK0rrmUxd
而水熊蟲這種抵禦紫外角的色素科學結構，還需進一步的研究才能確立。472Please respect copyright.ＰＥＮＡＮＡJteCmM9slU
