Whales and dolphins are mammals and breathe air into their lungs, just like we do. They cannot breathe underwater like fish can as they do not have gills. They breathe through nostrils, called a blowhole, located right on top of their heads.

Which marine animal has a blowhole on its head?
blowhole: (in biology) Nostrils on the top of the head of a cetacean (whale, porpoise or dolphin) through which the animal breathes. Toothed whales (like orcas) have one, baleen whales, such as right whales, have a pair.
How does a blowhole help a dolphin?
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.
What is the breathing organ of dolphin?
Unlike fish, who breathe through gills, dolphins breathe air using lungs. Dolphins must make frequent trips to the surface of the water to catch a breath. The blowhole on top of a dolphin's head acts as a "nose," making it easy for the dolphin to surface for air.
Why do whales breathe air?
Whales cannot breathe in water because they need to get oxygen from the air, so they have to come up to the surface to breathe. ... It turns out that whales are descended from other mammals that evolved on land, and these land mammal ancestors were breathing oxygen from the air using their lungs (like us).
Can a whale swallow a human?
Whales, in general, are not capable of swallowing a human being and therefore will not eat you. However, there is a species of whales that does pose a legitimate challenge to that general theory: sperm whales.
Do orcas spout water?
Breaching: The humpback whale and orca will propel themselves out of the water while landing upon their backs or stomachs. When doing so, they make a large splash that can be both seen and heard from large distances!
What is the blowhole called on a dolphin?
In cetology, the study of whales and other cetaceans, a blowhole is the hole (or spiracle) at the top of the head through which the animal breathes air. In baleen whales, these are in pairs. It is homologous with the nostril of other mammals, and evolved via gradual movement of the nostrils to the top of the head.
Do whales spout water?
Both baleen and toothed whales breathe through blowholes--the whale's version of nostrils. The telltale spouts that are formed on the surface occur when whales expel warm air that meets colder air on the surface and condenses into small water droplets.
Do dolphins spout water like whales?
During the powerful exhale, dolphins will spray up water at the surface of the ocean, producing what is referred to as a dolphin “spout”. When navigating the deep blue in search of marine life, many boat captains will use whale and dolphin spouts to identify species from far away!
What is respiratory organ in crocodile?
Like all reptiles, crocodiles breathe with lungs rather than gills. Lungs are evolution's solution to respiration issues faced by the first lower life forms that tentatively crept out of the water to eventually live on land full time.
How does cockroach breathe?
Roaches don't breathe through their mouths. Instead, oxygen enters their bodies through small openings located on their thorax. These breathing holes are called spiracles. The oxygen travels throughout a system of trachea tubes, and is distributed to all parts of the insect's body.
Do dolphins inhale through their blowhole?
Blowhole. Just like other mammals, they need to breathe for their bodies to function. 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.
How does a shark breathe?
Sharks don't have lungs, but they do have to breathe oxygen to survive. Instead of breathing air, though, sharks get oxygen from the water that surrounds them. ... The breathing process for sharks begins and ends with their gills, which they use to both extract oxygen from water and rid their bodies of carbon dioxide.
How do Grasshopper breathe?
For insects, respiration is separate from the circulatory system. Oxygen and carbon dioxide gases are exchanged through a network of tubes called tracheae. Instead of nostrils, insects breathe through openings in the thorax and abdomen called spiracles.
How do Orcas sleep?
How do orcas sleep? Orcas sleep in a very different way to humans. ... They only close one eye when they sleep; the left eye will be closed when the right half of the brain sleeps, and vice versa. This type of sleep is known as unihemispheric sleep as only one brain hemisphere sleeps at a time.
