研究員在紐西蘭發現一隻會用口呼吸的賀氏矮海豚!一般海豚會浮到水面用氣孔呼吸,但這隻海豚的氣孔可能有異物堵住或肌肉受損,所以自己學會了刻意移動了喉嚨,然後直接用口呼吸!

researchers discovered an endangered hector’s dolphin that breathes through its mouth! usually dolphins would breath with there blowholes, but this dolphin could have suffered a blockage in its blowhole, so it learned itself to withdraw its larynx and to breathe with its mouth!
