Top best answers to the question «Why do dolphins have blowholes»
They breathe through nostrils, called a blowhole, located right on top of their heads. This allows them to take breaths by exposing just the top of their heads to the air while they are swimming or resting under the water.
Instead of nostrils, dolphins have a blowhole at the top of their head. When they come to the surface for air, the blowhole opens, allowing them to breathe. When they head back under, the blowhole tightly closes under a thick layer of muscle. This prevents water from entering.
- A nerve mechanism alert the dolphin when the blowhole is out of the water, so it can blow out the air and breathe in again. Strong muscles close the blowhole when dolphins dive into the water to avoid drowning.
