有民眾日前在澳洲的普里姆羅斯沙灘 (Primrose Sands) 跑步時,發現1隻「長著雙手」的魚,且這稀有魚種距離上次被發現已是近20年前。對此,聯邦科學與工業研究組織 (CSIRO) 也驚訝地表示,「直到這次的發現前,我們還以為這種魚已經在當地滅絕了」。
事實上,這種稀有魚種被稱作「斑點疣躄」(handfish),因魚鰭長得像人類的手部或動物前肢,又名「斑點長手魚」,所謂的「手」就是牠們用來行走的魚鰭。目前,人們只在澳洲東南部水域發現過牠們的蹤影。
據《每日鏡報》報導,亞爾 (Kerri Yare) 日前在澳洲塔斯馬尼亞州的普里姆羅斯沙灘上跑步時,看到了「斑點長手魚」,她說牠看起來就像小河豚或蟾蜍,但仔細觀察後,卻發現其獨特形狀的鰭,在當時她也不敢相信自己的眼睛,更不時發出驚嘆。

事後,聯邦科學與工業研究組織 (CSIRO) 的迪瓦恩 (Carlie Devine) 表示,「斑點長手魚」目前在世界上僅存2000隻,她還說「直到這次的發現前,我們還以為這種魚已經在當地滅絕了」,而幾年前組織也曾試圖尋找「斑點長手魚」,但卻一無所獲,但有了這次的發現後,讓他們有再次尋找的信心。
據該組織稱,「斑點長手魚」是第1種被國際自然保護聯盟列為極度瀕危的海洋魚類,其原因是近岸挖泥漁業和入侵物種破壞其棲息地,此外由於牠們體積小,所以也很難找到。
迪瓦恩說,目前組織也正在努力防止該物種滅絕,除了在其自然棲息地引入人工產卵棲息地外,水族館還飼養了這種魚,這不僅可以阻止滅絕,還可以繁殖魚類,並保證幼魚的安全,直到長大一些,就會把牠放回河裡,希望此舉能增加牠們在野外的數量。
Spotted handfish preparing for another day of avoiding humansSpotted: a critically endangered handfish! Recently, we've had more news about these elusive creatures than we can count on one hand(fish). This week's news is that a runner spotted a critically endangered spotted handfish (Brachionichthys hirsutus) in Primrose Sands, Tasmania. Unfortunately the fish was dead, but it's exciting evidence of life of a population we'd thought was locally extinct since 2005. Once plentiful along Tasmania’s east coast, the number of spotted handfish has plummeted over the past three decades. But the fish are also solitary and small, making them very difficult to find. We estimate there are only about 2000 spotted handfish left in the wild. That's why we've been working for two decades to conserve them.
