Whales do not have gills, they have lungs. All whales take air into their respiratory system from a blowhole, which acts as a nostril and is located on the top of a whale's back. ChaCha on!

About Gills
Gills are what fish use to breath underwater. They pull dissolved oxygen out of the water the same way we pull oxygen out of the air.
About Whales
The largest mammal on the planet is the water-dwelling whale, even larger than the largest of the dinosaurs. There are many different types of whales, ranging in size from the dwarf, or pigmy, sperm whale, that is 8.5 feet long up to the blue whale, that is about 115 feet in length. The blue whale was about the same length as a Brachiosaurus, yet the whale's weight is about 170–190 tons, while in comparison the Brachiosaurus weighed only about 70-80 tons.
