blowholes

Whale breathing openings

Blowholes are openings through which air or water escapes.

The blowhole on a whale or dolphin is the nostril on top of its head, through which the animal breathes and expels dramatic spouts of water vapor.

Coastal blowholes are rock formations where waves force water through narrow passages, shooting spray into the air.

In manufacturing, blowholes are unwanted air pockets trapped in castings or welds.
