Used specifically for marine mammals like whales, indicating the act of breathing. During the boat trip, we observed the whale's blowhole action.
Pro Tip 2/3
Not Always Visible
'Blowhole' is not always seen; it is often submerged and visible only when the animal breathes. The dolphin's blowhole was visible only for a few seconds.
Pro Tip 3/3
Sound Accompaniment
The term may imply the sound made by the spout of water and air. We heard the loud sound from the whale's blowhole before we saw the spray.
