Knowing the whales - Right whale and the blowhole

Right whale and the blowhole in Peninsula Valdes
Blowholes or the whales equivalent to our nostrils, are situated on the top and back of the head and have powerful muscles that close them and prevent water entering the lungs. When breathing out, the animal expels two columns of moist air vapour particles, mixed with secretions from the air passages and lungs.

These columns or clouds rise forming a “V” which can reach 5 meters in height. By the shape of the blow, we can distinguish a right whale from other species, such as orcas or dolphins, which have a single blowhole.
