Boojho has seen in television programmes that whales and dolphins often come up to the water surface. They even release a fountain of water sometimes while moving upwards. Why do they do so?
Answers
Like other mammals, Even dolphins and whales respiratory organs are Lungs.So they have to come to the surface of the water regularly.
The nostrils of whales and dolphins are located at the top of their heads called as Blowholes.
So they exhale and inhale air through these blowholes.
hence, their exhalation looks like releasing fountain of water. some water in the passage comes out through blowholes also the water vapour in the exhaled air look like droplets in cold weather together giving that look.
Whales and dolphins often comes up to the water surface. They even release a fountain of water sometimes while moving upwards because the water from their passage come upwards which appears like fountain. They come upwards to take in fresh air.

We need to find the solution to the question
Whales and dolphins belong to the same category. They both can come up to the surface of the water or ocean and also eject the stream of water while moving upwards. This is mainly because they tend to breathe the fresh air and ejects carbon dioxide. The hole which ejects water is called a ''blow hole''. And when they breathe air out of it, it appears like a fountain of water. Blowholes are surrounded by muscles that keep them closed when they are underwater.
