They breathe through their blow holes.

A killer whale breathes through a single blowhole on top of its head. •

The blowhole is relaxed in a closed position. To open the blowhole, a killer whale contracts the muscular flap covering the blowhole. •

A whale holds its breath below water. •

A killer whale opens its blowhole and begins to exhale just before reaching the surface of the water. • At the surface, the whale quickly inhales and closes the muscular flap.
Orcas Breathe with lungs. They take in air at the surface of the water through a blowhole located near the top of the head.
Orcas are mammals, so they can not get air from the water with gills. Instead they have a hole on the top of their head called a blow hole. Toothed whales have 1. Baleen whales have 2. Orcas are toothed whales so of course they have 1. Baleen whales have their holes right next to each other, and they only breath through 1. Orcas like all whales and dolphins can close their blow holes before going under water. When the whale comes up to breath, it blow out the air and takes another breath. Sailors used to tell what kind of whale they were looking at by the height and angle of the blow. As the air comes out, so does some water that was on top of its blowhole. When an orca breaths it looks like it is shooting up a fountain of mist!
The killer whale, like other dolphins and whales, has a blowhole on the top of its head which it breaths through while surfaced in the water.
Orcas breath through their blowhole, which is at the top of their head. When they breath through it, you can see mist shoot up into the air.
