Rare dolphin turns pink when it's angry
A rare albino dolphin that can go from white to pink when it is feeling flushed is pulling in the crowds at a water park in Japan.
日本的一家水上公园中,一只珍稀的白化变种海豚在情绪激动的时候身体颜色会从白色变为粉色,这一奇观吸引了许多游客在此驻足流连.
Although bottlenose dolphins (Tursiops) are usually grey, this extremely rare creature is an albino and has no colouration – apart from a tendency to turn pink when feeling flushed.
尽管宽吻海豚通常是灰色的,这只极为罕见的宽吻海豚却因为是白化变种而没有色彩——除了兴奋时会变粉.
Photos show how the animal is normally white, and occasionally pink when swimming along regular coloured grey dolphins.
从照片中可以看出,这只海豚平常是白色的,和寻常的灰色海豚一起游泳,偶尔才会变成粉色.
Albino mammals are born without melanin, which gives the colour to both eyes and skin, and albino dolphins are extremely rare.
白化哺乳动物在出生的时候体内就不含黑色素,而黑色素会让动物眼睛和皮肤有颜色.白化变种海豚是非常罕见的.
In fact this specimen is believed to be only the second one ever put on display in an aquarium after it was purchased from fishermen.
事实上,据认为这是有史以来在水族馆展出的第二只白化变种海豚,这只海豚是从渔民那里买来的.
And they may well have been doing the animal a favour, as albinos are easy prey out at sea as they lack the colouration to blend in like their grey coloured relatives.
渔民们把这只海豚卖到水族馆可能倒是帮了它一个大忙,因为这只海豚在海上很容易被捕猎者发现,因为它不能像它灰色的同胞一样混迹于大海中.
