蝴蝶魚

(蝴蝶魚科蝴蝶魚屬)

鎖定
蝴蝶魚是蝴蝶魚科蝴蝶魚屬魚類,又名蝶齒魚。該魚體長約12釐米,身體褐色,色彩單調,體形並無特異之處,但其胸腹鰭與一般魚類不同,胸鰭寬大,腹鰭各鰭條彼此分離,只在基部相連。雌雄容易區別,雄魚體色較深,臀鰭變粗大,適於交配;雌魚有明顯的不規則花紋,臀鰭正常。 [3]  游泳時似飛行中的蝴蝶,故名蝴蝶魚。蝴蝶魚約有18屬190種,中國產蝴蝶魚科有14屬約57種。 [4] 
蝴蝶魚分佈於大西洋、印度洋和太平洋的熱帶和暖温帶海洋珊瑚礁海域,主要分佈於南海,只有少部分進入東海南部。蝴蝶魚生性活潑,行動迅速,性膽怯,常隱身於珊瑚礁石間。肉食性或雜食性,以浮游甲殼動物、珊瑚蟲、蠕蟲、軟體動物和其他微小動物為食。對水質要求較高,要求海水的相對密度為1.020-1.023,水温26-30℃,pH在8以下。 [4]  繁殖方法不詳,據説雌魚受精後,精子可保存在體內很長時間,因而在以後多次產卵時不必再度受精即可產出受精卵,受精卵含在雌魚口內孵化。 [3] 
蝴蝶魚多用作觀賞魚。 [4]  蝴蝶魚是“一夫一妻”的絕對捍衞者,它們總是成雙成對地出現和嬉戲,當一隻魚在進食的時候,另一隻會在旁邊四處巡邏保衞。 [5]

蝴蝶魚形態特徵

蝴蝶魚 蝴蝶魚
體呈菱形或近於橢圓形,且十分側扁。口小,端位,略可伸縮;頜齒細長,在上下頜形成刷毛狀之狹長齒帶。前鰓蓋骨平滑,但幼魚可能具有鋸齒或被有突棘。體被中或小型之弱櫛鱗或圓鱗。側線完整,呈弧形,但不明顯。幼魚之頭部,因長有骨質板,而被稱之Tholichthys。背鰭連續,硬棘部和軟條部間有淺缺刻;腹鰭胸位,具腋鱗;尾鰭一般截形或圓形。 [1] 

蝴蝶魚生活習性

蝴蝶魚大部分都生活在20公尺以內的淺水水域,是很典型的日行性魚類,白天出來找東西吃、交配,晚上才躲在礁洞裏面休息。覓食時,或羣遊,或成對,或獨遊。食性變異大,有的從礁岩表面啄食躲藏在縫隙裏的小型無脊椎動物及藻類,有的在水層中撿食浮游動物,有的只吃活珊瑚的水螅蟲等。行動迅速,稍受驚動即躲入珊瑚礁或岩石縫中。它們生活史中需要經過一段長時間的漂流期,而使得人工繁殖不易成功。
