From Pathfinder Wiki
- D: They breathe air just like us. This means that they must hold their breath while under the water. A Sperm Whale can hold its breath for 30 minutes. When they want to breathe they come to the surface, blow out moist air from their lungs and snatch a new breath. Their nostrils are called blowholes. Baleen whales have two blowholes and toothed whales one blowhole. The whale hunters could tell what sort of whale it was by the shape of the spout blown out.
