科普專欄–薯不揀單 - 三十秒科學–老鼠的習性

老鼠與人類均是雜食性動物(Omnivores)，而老鼠每日約有80%的食物均是在晚上進食的。866Please respect copyright.ＰＥＮＡＮＡ7oqvI9GTx5

若果晚上(>12hr)不讓老鼠進食的話，牠們的體重平均來說會減去10%左右。866Please respect copyright.ＰＥＮＡＮＡ1B7LcIdjjK

約連續22小時不讓牠們進食後，牠們腸道便會變得空空如也。866Please respect copyright.ＰＥＮＡＮＡdZ9hnotWPZ

（圖2）老鼠是夜行性(Nocturnal)動物，牠們眼球內負責辨認顏色的錐體少得非常可憐，純粹依靠感應紫外線的接受器，透過紫外線的強弱了解世界。866Please respect copyright.ＰＥＮＡＮＡJWyjq6wgrW

只不過的是，牠們大多偏愛清晨時份進行交配行為。866Please respect copyright.ＰＥＮＡＮＡh3Q0OKueRR

（圖3）老鼠的感覺毛 (Whiskers)有著感測聲音的能力，其排列大多是五橫行分佈，每行約有五至九點。866Please respect copyright.ＰＥＮＡＮＡaxlJ6bYomY

越靠近嘴部的感覺毛，所能感測的聲音頻率亦越高。866Please respect copyright.ＰＥＮＡＮＡXdNcwW3pGa

人類最高能感測至20k Hz的音頻，而老鼠最高則能去到90k Hz，高於20k Hz的超聲波(Ultrasound)同時亦是老鼠聽力最為敏感的區域。866Please respect copyright.ＰＥＮＡＮＡ9nmveCkUtc

利用超聲波驅逐或者招來老鼠，或許可行。866Please respect copyright.ＰＥＮＡＮＡxh8TIo2ztG
