Can you tell what that small, black thing is? It isn't dirt, and it isn't a stick. It's a worm.
Most worms live in the ground. They dig down into dirt to make their homes. This worm also digs deep to make its home, but this worm digs into snow, not dirt. It's called an ice worm.
The ice worm in this picture was found underneath 3.6m of snow. Can you imagine trying to live in a place that cold? Scientists want to know how the ice worm can live in such cold temperatures.
They think that if the ice worm can live without a lot of heat or light, maybe there could be living things on distant planets that are much colder than Earth. (Taipei Times)
你看得出來那個小小黑黑的東西是什麼嗎？不是泥巴，也不是一根樹枝，它是一隻蟲。
大部份的蟲住在地底下，它們鑽進土裡築巢，這隻蟲也得鑽出自己的巢，不過這隻蟲是鑽進雪地裡而不是泥土裡，它叫做冰蟲。
照片裡的這隻冰蟲是在雪地下三點六公尺被發現的。你能想像住在這麼冷的地方嗎？科學家想知道為什麼冰蟲能在這麼冷的溫度存活。
他們認為，如果冰蟲可以在欠缺光和熱的環境存活，也許在比地球冷的遙遠星球上也會有生物存在。
