They need a blowhole to breathe with. They come up to the surface out of the water and "breathe in air" through the blow-hole. Then they can go back down into the water for a period of time until they need to re-surface for more air.
Toothed whales, like dolphins and porpoises, typically have one blowhole on top of their heads. This singular blowhole allows them to quickly surface, take a breath, and expel air before diving back underwater.
A gray whale's respiratory system consists of blowholes located on the top of its head, which it uses to breathe air at the water's surface. The blowholes connect to the lungs, allowing the whale to exchange gases necessary for respiration. Gray whales are mammals and require oxygen from the air to survive.
Whales use respiration to gain energy when they swim at the surface. They breathe air through their blowholes, taking in oxygen which is then transported to their muscles for cellular respiration. This process helps them convert oxygen and nutrients into energy efficiently, allowing them to swim and perform other activities. Fermentation is not a primary energy source for whales, as it occurs in anaerobic conditions and is not suited for their aerobic lifestyle.
Whales are mammals, not fish, and have unique adaptations to live in water, such as a thick layer of blubber for insulation and buoyancy. They are known for their complex communication abilities, including using songs and calls to communicate with others in their pod. Some whale species, like the blue whale, are the largest animals on Earth, growing up to 100 feet in length.
If a fish doesn't have gills it can't breathe so it can't get oxygen
All types of whales have blowholes because they need them to breathe. As we have noses, whales have blowholes. Porpoises and dolphins have blowholes as well.

Whales and dolphins.
All whales have a blow hole.
Usually they have one Baleen whales have two blowholes. Toothed whales have only one.
Yes all whale have blowholes because they are mammals.
They have blowholes.

There are currently 88 known species of whales, dolphins, and porpoises that have blowholes, so there are potentially 88 blowholes in the world.
For threm to breathe and get oxygen.
