Friday, May. 14, 2010 11:35 p.m. 因為一則關於挪威發現皇帶魚的新聞，再次激發起對海洋生物的好奇心。皇帶魚英文名是Oarfish，日本稱之為龍宮之使者，銀色、長型，長有粉紅色背鰭，可長達十幾米。在深海生活，臨死或生病時會浮上水面，獵食時會保持奇特的垂直姿態，即身體與水面成直角。游泳方式與其他魚不同，身體雖然長，前進時卻不需扭動，只要波浪型擺動背鰭就可以推動一直保持筆直的身體前進。 拍攝以上片段的科學研究員Benfield，同時發現一種名為manefish的怪魚，此魚靠捕食一種叫siphonophore的東東維生。那siphonophore究竟是甚麼？sophonophore管水母，貌似水母但並非水母，也不是一個個體，而是無數的個體糾結而成的colony。一個colony由負責不同功能的個體(zooid)組成，負責消化、游泳等等，大家形態與作用都不同，但又必須互相依賴才能生存。以劇毒聞名的葡萄牙戰艦／僧帽水母，英文名Portuguese Man O' War，原來就是siphonophere而非jellyfish。 留意尾段出現，企圖襲擊Man O' War的藍色怪物，是一種叫Glaucilla marginata，愛倒轉浮於水面的裸腮類動物nudibranch（即海蛞蝓sea slug的一種）。個樣超怪。 這是讀者文摘出版的Oceans and Islands，我家有一本中文版，叫海洋與海島，成4-5cm厚，自我有意識以來就不斷翻看。小時候認識藍腳鰹鳥(blue-footed booby)、波里尼西亞的帆船、海兔(sea hare)、鸚鵡螺、復活節島的神秘石像等等，全都拜這本寶書所賜。家裏還有一本同是讀者文摘出版的大自然之趣，介紹陸地上的動植物居多，圖片同樣精彩，但不知怎的我還是偏愛海洋與海島多一點。 --- will be described by yuen as 宅女 if she saw this. --- actually i wanted to be a scientist when i was small. well at first i told mum and dad i wanted to be a pianist when i started learning to play the piano at four. dad said i would starve to death but mum said it's great (because she's the one who made me take piano lessons >:| ). some time later i saw UST's campus while travelling to saikung on the bus. i thought it's beautiful, and i said i wanted to be a scientist in the future. this time both mum and dad were happy. around the same time i started to become practical and thought i should be a teacher. this time, both parents said 千祈唔好 although they were both teachers. |
