coelacanth 腔棘魚
coel, 空的，詞源同hole. -ac, 尖，尖刺，詞源同acid. 因支撐魚尾的尖鰭為空鰭而得名。該魚為一種7000萬(wàn)年前的古魚，僅存化石保留，1938年在南非東南海岸一張照片顯示南非漁民捕獲了一條形似這種魚化石的魚，但是當(dāng)魚化石專家趕到現(xiàn)場(chǎng)的時(shí)候，已經(jīng)被漁民吃的僅剩骨頭。但關(guān)于這種魚可能帶存活的消息傳開后，激動(dòng)了全球各地的漁民尋找這種魚的熱潮。
英文詞源
- coelacanth (n.)
- 1857, from Modern Latin Coelacanthus (genus name, 1839, Agassiz), from Greek koilos "hollow" (from PIE root *kel- (2); see cell) + akantha "spine" (see acrid). So called from the hollow fin rays supporting the tail. Known only as a fossil, the most recent one from 70 million years ago, until discovered living in the sea off the east coast of South Africa Dec. 22, 1938. The specimen was described by Marjorie Courtney-Latimer, who wrote about it to S.African ichthyologist J.L.B. Smith.
I stared and stared, at first in puzzlement. I did not know any fish of our own, or indeed of any seas like that; it looked more like a lizard. And then a bomb seemed to burst in my brain, and beyond that sketch and the paper of the letter, I was looking at a series of fishy creatures that flashed up as on a screen, fishes no longer here, fishes that had lived in dim past ages gone, and of which only fragmentary remains in rock are known. [J.L.B. Smith, "Old Fourlegs: The Story of the Coelacanth," 1956]
