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 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
No, whales are not omnivores. They are classified as carnivores because they primarily feed on fish, squid, and other marine animals.
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.

There are currently 88 known species of whales, dolphins, and porpoises that have blowholes, so there are potentially 88 blowholes in the world.
