...有些甚至是較年老的；而無斑點的海豚應絕大多數是年老的雌性。雄性方 面，少年及亞成年個體均會停留在多斑點的階段較久，當中一些成年個體仍是滿 身斑點。部分已達性成熟的雄性及較年長的雄性會進入中度斑點的階段，但只有 少數年老的雄性會達到少斑點及無斑點的階段。一些擱淺海豚的資料亦進一步證 實上述海豚身體顏色與成長關係的推測。 根據海豚身體斑點的多寡及目擊紀錄的歷史，研究員亦估算出個別海豚的壽 命，發現大部分被辨認的海豚都是已達至性成熟的成年個體，當中很多應已超過 二十歲，甚至是三十歲以上。中華白海豚較長的壽命對此種群的長期健康發展甚 為重要。另外，研究亦發現雌性一般較雄性長壽，這可能與雄性海豚身體積存較...

...。高速渡 輪所發出的聲響，亦遠高於沒有太多船隻出現的水域之背景噪音水平，此證明當 一些繁忙航道與海豚重要生境重疊，行經該航道的高速船所發出的聲響將大幅提 高水底噪音的水平，而影響海豚在該處的活動。由於這些船隻以高速航行，當它 們在短時間內靠近海豚時，牠們未必有時間作出合適的反應以遠離這些船隻；若 同時有數隻高速船在海豚周圍掠過，尤其是當這些船隻航行的速度、及與海豚保 持的距離經常改變以致難以揣測，海豚為要逃避船隻而所承受的壓力亦因而增 加，令牠們更易被高速船所撞擊，或逼使牠們放棄一些原適合作覓食活動的生境。 另一項有關高速渡輪對本地中華白海豚及江豚的影響評估發現，在 1999- 2010 年間，來...
