“ we have two species of resident cetacean , the chinese white dolphin and finless porpoise . there are some highly endangered green turtles returning to breed and nest locally . over 600 species of fish are recorded and more than 50 species of reef - building corals are found in our waters , “ she said 中華白海豚和江豚是在本港水域定居的兩種鯨豚類動物,高度瀕危的綠海龜亦不時返回香港繁殖,而香港水域亦記錄到超過六百種魚類和五十多種石珊瑚。

Two years later , in the himalayan foothills of northern pakistan , gingerich ' s team found another weird whale clue : a partial braincase from a wolf - size creature ? found in the company of 50 - million - year - old land mammal remains ? that bore some distinctive cetacean characteristics 兩年后,在巴基斯坦北部的喜馬拉雅山丘陵地帶,金格瑞西的團隊找到另一個古怪的鯨豚線索:一個不完整的腦顱,似乎是個體型像狼的動物,可是帶有一些鯨豚類獨有的特徵;與它同時出土的都是5000萬年前的陸棲哺乳類化石。

Trainers of captive dolphins and small whales often remark on their animals ' responsiveness to being touched or rubbed , and both captive and freeranging cetacean individuals of all species ( particularly adults and calves , or members of the same subgroup ) appear to make frequent contact 訓練者捕獲海豚和小鯨魚經常評論它們的動物反映當被撫摸或是摩擦的時候,并且無論是捕獲還是放養的所有種類的鯨類個體(尤其是成年鯨和幼仔,或是用一個子群中的成員)表現出頻繁的接觸。

“ we have two species of resident cetacean , the chinese white dolphin and finless porpoise . there are some highly endangered green turtles returning to breed and nest locally . over 600 species of fish are recorded and more than 50 species of reef - building corals are found in our waters , “ she said 中華白海豚和江豚是在本港水域定居的兩種鯨豚類動物,高度瀕危的綠海龜亦不時返回香港繁殖,而香港水域亦記錄到超過六百種魚類和五十多種石珊瑚。

Other animals include the red deer , fox , badger , rabbit , otter , grey seal , common seal , red squirrel , hedgehog and many bat and cetacean species . the only amphibians are a single species each of frog , toad and newt . there are no snakes in 其它動物包括紅鹿、狐貍、獾、兔子、水獺、灰海豹、普通海豹、紅松鼠、刺猬和很多蝙蝠類和鯨類動物。唯一的兩棲動物是青娃、蟾蜍和蠑螈,且都只有一個品種。

With pakicetus showing up around 50 million years ago and mesonychids known from around the same time in the same part of the world , it looked increasingly likely that cetaceans had indeed descended from the mesonychids or something closely related to them 巴基鯨大約在5000萬年前出現,而同一時間同一地點也有中爪獸存在,鯨豚從中爪獸或?們的近親演化而來的看法,似乎越來越接近真相了。

Southern cross university has a dynamic research profile , participating in seven national co - operative research centres , leading the way in disciplines as diverse as plant genetics and cetacean research 南十字星大學的研究實力雄厚,參與了全國七個合作研究中心,在植物遺傳學和鯨類研究科目上引領著發展潮流。

Although the senses of taste and smell appear to have deteriorated , and vision in water appears to be uncertain , such weaknesses are more than compensated for by cetaceans ' well - developed acoustic sense 雖然觸覺和嗅覺已經退化,在水中的視覺也不能確定,如此微弱使更多的補償在鯨類很好的聽覺上。

They have also unearthed some clues from the ensuing oligocene , when the modern suborders of cetaceans ? the mysticetes ( baleen whales ) and the odontocetes ( toothed whales ) ? arose 在隨后的漸新世地層中,他們也找到了一些線索;須鯨亞目(有鯨須的鯨魚)與齒鯨亞目(有齒的鯨魚)就是在那時候分化的。

Although the fossil skull lacked the anatomy necessary for hearing directionally in water ( a critical skill for living whales ) , it clearly had the diagnostic cetacean ear traits 雖然那個化石頭骨缺少在水中聽方位(現生鯨豚不可或缺的本領)所需的構造,卻有鯨豚類特有的耳朵特徵,一點都不含糊。

Calling them “ on the whole , the most peculiar and aberrant of mammals , ” he inserted cetaceans arbitrarily among the other orders 他認為鯨豚整體而言,是最奇異、最歧出的哺乳類,并為?們單獨設立了鯨目,與其他目并列于哺乳綱中,不特別交代?們的來歷。

After mating , the two cetaceans linger side by side , stroking one another with their flippers and finally rolling together in what looks like an embrace 在交配以后,兩條鯨肩并肩地纏綿著,用鰭彼此愛撫著,最后好像是相互擁抱著,開始上下翻騰。

Lacking fur and hind limbs and unable to go ashore for so much as a sip of freshwater , living cetaceans represent a dramatic departure from the mammalian norm 現生的鯨豚類沒有毛發、后肢,連上岸喝一口水都辦不到,與一般的哺乳類有很大的差異。

Some of the senses that we and other terrestrial mammals take for granted are either reduced or absent in cetaceans or fail to function well in water 一些我們及其他陸地哺乳動物的感官被認為不是減少就是缺少在鯨類身上或不能在水里運作得很好。

Similarly , although at least some cetaceans have taste buds , the nerves serving these have degenerated or are rudimentary 相同的,盡管至少一些鯨魚還有味蕾,但服務的神經已經退化或根本未發育。

An examination of the functioning of the senses in cetaceans , the group of mammals comprising whales , dolphins and porpoises 一項對鯨類感官機能的檢查,這組哺乳動物包括鯨,海豚和鼠海豚。

From1996 to 2004 , how many stranded cetaceans were found in hong kong waters 從1996至2004年,一共有多少條擱淺鯨豚動物在香港水域被發現?
