Dolphins are one of the most unique and intriguing marine animals, but when it comes to dolphins, there are some questions that may not come up often enough or that you may forget to research ahead of time—like whether dolphins have blowholes like whales and porpoises do. Read below to know.
The Dolphin, like other mammals, needs air to function. So, instead of nostrils, the dolphin has a blowhole at the top of its head. When they come to the surface the blowhole opens, allowing them to breathe. Once under the surface, the blowhole closes.
Dolphins and whales both live in the ocean and they are related to each other in many ways, but one way they are different is how they breathe. Both dolphins and whales have blowholes, which look like little holes on the top of their heads, but you can tell them apart by how they breathe out of them.

Why do dolphins have blowholes?
Dolphins are some of the most unique marine animals, with their own set of physical and behavioral traits that can only be found in this species. One of the most fascinating of these traits is the dolphin’s blowhole. While it seems like one simple hole, there’s actually much more to it than meets the eye! Read on to learn about why dolphins have blowholes.
Since dolphins don’t have gills to breathe, 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 above the water’s surface without taking in water or exposing any other part of their bodies that could be vulnerable to predators underwater.
Dolphins have blowholes to breathe and to communicate. This is how many animals communicate. The dolphin uses its blowhole to take in air as they are swimming through the area.
Dolphins also use their blowholes when they want to stay hidden from predators and other dangers. This skill keeps them safe while at the same time enabling them to easily get air during a hunt or when needing to quickly escape predators.
What do Dolphins Do with their Blowholes?

Dolphins aren’t only known for their intelligence, their grace in the water, and their playful nature, but also for their blowholes. While we may have used the word blowhole to mean an opening in a whale or dolphin’s head that can get the air and water out, it actually refers to the nostril of these mammals. Let’s explore more of what dolphins do with their blowholes!
A dolphin’s blowhole serves as an outflow for excess water when the mammal surfaces to breathe or as an intake for water when it dives back into the sea. It also helps regulate its body temperature and, during play, functions as a built-in sprinkler system when the dolphin leaps high into the air above the surface of the water.
Dolphins have a blowhole on top of their heads that lets them breathe when there is an abundance of water around. When they are jumping around in the sea or other bodies of water, they release air through their blowholes so that they do not become waterlogged.
Whales vs Dolphins Blowholes
Whales blow holes have been quite popular for a long time however not much has been known about dolphins blowholes. Let’s find out the difference between whales and dolphins.
A whale’s blow holes evolved over time because of a need for more oxygen. When a whale dives deeper, it needs to be able to breathe in more air quickly, which is accomplished with two blowholes. Dolphins do not need these holes because they generally only swim a few meters below the surface, so they have evolved with one blowhole altogether.
Can Dolphins Breathe on Land?
Dolphins are aquatic mammals and must live in the water to survive, but does that mean they can’t breathe on land? You might be wondering how dolphins can survive without water, so in this article, we will explore the ins and outs of this fascinating species and find out if dolphins can breathe on land.
Dolphins have been swimming in oceans and lakes for millions of years, but they still can’t breathe on land. Their bodies aren’t made to handle the change in pressure that comes with moving from water to air. It might seem strange that such an intelligent and social animal would be unable to adapt its body to function on land, but dolphins are built specifically to swim in water, not on land.
Apart from this, since there is a lack of fish supply on land this is the other reason they cannot survive on land.
Why Can’t Dolphins Breathe On Land?

Dolphins are amazing animals and they are often the star of aquariums and zoos around the world. But one question that’s always bothered many people is “Why can dolphins breathe underwater but not on land?” Read below to know.
Their Skin Will Dehydrate and Overheat If a dolphin approaches land, it will immediately begin to sweat. The reason for this is because the pressure in their body tissues changes when they try to breathe at sea level or on land. This change in pressure causes an increase in heat production by the body, which can be extremely dangerous if it is not controlled.
However, despite the fact that dolphins can eat fish and other aquatic species, their diet is largely dependent on liquid. That’s right — they live off of water and this is why dolphins can never take off their skin when they are on land because they will overheat if they don’t get moisture back into their body through drinking water or eating fish.
Conclusion
Dolphins have blowholes simply because they need to breathe, just like fish, elephants and us humans. Dolphins blow holes not only for breathing, but also help them communicate with each other. Dolphins actually use their blowholes to make noise and helps them to communicate with other dolphins.
