Unlike a fish, a seal cannot breath underwater, so it must come to the surface and into the air to breath. When the surface of the water is covered with ice, seals still need air, and they must break through to reach it. Since breaking thick ice isn't easy, they tend to use the same holes over and over.
Seals are mammals. They Breathe air with lungs, through mouth and nostrils. They need to be able to poke their head above the water to Breathe. Ice lies on top of the water. If it wasn't for breathing holes, the seals would drown. Since it's Cold, the holes try to freeze over, so the seals have to work on keeping them open.
Worn-down teeth , and with that, no more breathing holes is a common cause of Death for seals.

Seals breathe with lungs, just like you and I. If they didn't hold their breath under water they'd choke and drown.
they use their highly equipped heads to poke holes in the ice cream
Answer: spiracula (spiracle singular) adj spiracular; vent, orifice, passage, but mainly the holes in ice for and by seals
no they are not but may be soon since the ice is disappearing because we are polluting the earth. They may die because they cannot eat the seals because they usually wait next to the seals breathing holes but because the ice is melting the seals don't need the holes to breath in so the bear just sits there waiting for a seal to come up to the surface but no seals come.
No, harp seals can also keep holes open in the ice. That is were they escape from predators and it helps them breathe.
Larry, Moe and Curly. OK, seriously now, this is one of those "don't overthink it" questions: they're called breathing holes. No doubt there's an Inuit word for them, too, but I don't know it.
dolphins
they like dark boxes that they feel secure in and any hidey-holes. make sure they can get out when they want to and there are breathing holes!
The rubber shoould have tiny holes for air to escape, either fill these holes with silicone rubber or make bigger holes for more air to escape.
The abdomen
they breath out of their eye holes
those are the corals breathing hole 1 for breathing 1 for eating 1 for disposing watse. also they have those holes for other animals to hide in.
There is no harm or decline in the population of seals. Its just that seals usually spend most of their time under the ice sheet in the below freezing temperature of water below. Polar bears have to wait for a long time near the breathing holes that seals make before they get under the ice.When the seals come out to take in air again, the polar bears kill them. Since, they can stay underwater for hours together, it may seem that they are few in number.
those are their breathing holes
