In its external respiratory system, the right whale has 2 spiracles or nasal orifices, arranged in a V shape instead of just one like the killer whale. This characteristic allows identifying these giants of other marine mammals by means of the image that forms the exhalation of the air of their lungs. This mass of air when leaving with power flies the little water accumulated in the nasal surface of the hermetically sealed blowhole, until the exact moment of the exhalation. In a moment it expels a volume of 800 gals (3,000 liters ) of air, leaving a fleeting drawing in the air in the shape of a V and a characteristic audible sound several kilometers away. The trace of respiration is relatively short, V-shaped so that this species can be identified from a distance, especially if seen from the front or behind.
