Sea ponies: do they need to breathe air or not?

[Al-1701]

Sea ponies need their Mermaid-magic-ness or else I think sharks would eat them! Oh nooooo!

Maybe they're on good terms with the sharks.  Or just stay out of San Jose.

I remember an episode of "My Little Pony and Friends" where the sea ponies were trapped under the ice.  They didn't have any problems breathing then and guided the ponies to a far off destination from under the ice.

I know that there is a mammal... I forget what, than can swim under ice for days. It breathes by sticking its mouth on the ice itself and inhaling the outside air through the ice. Maybe Sea Ponies can do that too?

Is it a Narwhal you're thinking of?

Maybe, or some kind of seal?
