Dolphins usually breathe using their blowhole. But it now seems this is not a hard-and-fast rule. For the first time a dolphin has been spotted breathing through its mouth.
The finding reveals that dolphins can adapt their behaviour, as you can see in the video above.
“It demonstrates the behavioural flexibility of these animals,” says lead author Stephen Dawson of the University of Otago in New Zealand. “It has invented a novel work-around to circumvent a disability. However, the process is a bit clumsy, and clearly is nowhere near as efficient as the normal mode of breathing.”
