[貼圖] Triggerfish

Some fish, with their delicate features and calm poised attitudes, always appear ready for their close-ups. Others, like this teetering triggerfish, look like you’ve just snapped a Polaroid of them in the middle of wild weekend in Las Vegas.
To be fair, when expedition leader Enric Sala took this photo, the fish was essentially in the middle of a bath, getting the spa treatment from a tiny cleaner fish visible just below its eyes.





This triggerfish may have a comical appearance, but the wavelike motion of its fins and the peaceful inter-species partnership it’s displaying with the cleaner fish below its eyes add an unexpected level of beauty and inspiration.


I saw the same behavior (and perhaps even the same fish) today as I dove with our fish experts Jenn Caselle from Marine Science Institute, UC Santa Barbara, and Alan Friedlander of the US Geological Survey and University of Hawaii as they laid out rope and tape measures and identified and counted every fish that passed by that line.




At one point Alan signaled to me and pointed into the distance. There, its colors fading into blue from from all the water between us, was a triggerfish just like this one Enric had photographed up close the day before. Parasites were being nibbled off its body by an attendant cleaner fish.

As the cleaner fish did its work, the triggerfish rolled on its side, with its large top and bottom fins waving like the graceful wings of a manta ray. Having appreciated its comical qualities the day before, it was in a way humbling now to see it in person, moving beautifully, demonstrating peaceful inter-species partnership.

As Mark Hooper, one of our ship’s engineers said to me the other night, “It’s a beautiful planet we’ve got if you just take the time to look at it.”

Clown Triggerfish

Triggerfish 扳機魚也叫也扳機鲀、炮彈魚。是一種鲀類,是鱗魨科約30種淺水海產魚類的統稱,廣布於熱帶海洋。體較高,一般體色豔麗,鱗大,口小,眼位高。共同特征是背鰭棘3個,前兩個被認為有如槍之扳機結構,故魚得名扳機魚,即第一棘豎起後,第二棘作為「扳機」從後嵌入卡住;第二棘必須先撤回原位,第一棘才能放平。第一棘粗大而強,當被卡於直立位時,可使魚牢牢固定在保護性的岩礁縫隙。

有很多種。它門小小的口中有上下8顆像鑿刀一般尖銳有力的牙齒咬力甚強,連海膽等硬殼也能嚼碎。扳機魚又是一種領地觀非常強的魚類,特別在繁殖季節,為了保護巢區的安全,他們會襲擊任何接近的生物,包括潛水員,而且攻擊速度很快。

扳機魚也叫也扳機鲀、炮彈魚。是一種鲀類,是鱗魨科約30種淺水海產魚類的統稱,廣布於熱帶海洋。


分類
小醜扳機魚或稱大點扳機魚也是非常吸引人的魚類,這種魚身長50釐米,通常在太平洋、印度洋和紅海的溫暖地帶出現。

灰色扳機魚(Balistes capriscus)是鲀形目的一個代表型

畢加索扳機魚長約20-30釐米。之所以名為畢加索,可能源於身上大塊的現代畫圖案。畢加索扳機魚的背鰭具有硬棘,能樹立起來頂在珊瑚礁壁上。當大魚想吃它時,它就躲入礁穴中,用硬棘將自己牢牢的頂在礁壁上,以防止大魚吞噬。


泰坦扳機魚 Titan Triggerfish



體較高,一般體色豔麗,鱗大,口小,眼位高。共同特征是背鰭棘3個,前兩個被認為有如槍之扳機結構,故魚得名扳機魚,即第一棘豎起後,第二棘作為「扳機」從後嵌入卡住;第二棘必須先撤回原位,第一棘才能放平。第一棘粗大而強,當被卡於直立位時,可使魚牢牢固定在保護性的岩礁縫隙。 扳機魚及其近親都具有不同尋常的各種形狀。有的看起來像是盒子,而另一些則像是足球或餐盤。有時,它們都共有一些人們很難看到的特征:例如小小的嘴巴,與眾不同的牙齒,還有脊突上相對較少的椎骨。這類魚大約有350 個屬種,並且在全世界都能見到它們,多數扳機魚生活在近海的淺水區。


習性
有很多種。它門小小的口中有上下8顆像鑿刀一般尖銳有力的牙齒咬力甚強,連海膽等硬殼也能嚼碎。扳機魚又是一種領地觀非常強的魚類,特別在繁殖季節,為了保護巢區的安全,他們會襲擊任何接近的生物,包括潛水員,而且攻擊速度很快。 扳機魚 是和人一樣,晚上睡覺,白天活動的。扳機魚 雖然會咬人,但其實了解下它的習性也就不覺得危險了。
