Most Marine organisms require oxygen to survive. Most do not need to breathe air to do so as there is oxygen dissolved in water that can be absorbed.

There are a few organism, the smallest ones, that are anaerobic and do not require oxygen. Other than single cell organisms. they are rare.

Why is earths oxygen breathabale?

First of all it is spelled 'Oxygen'. It is not that Earth's Oxygen is more breathable than another planet's. We have just evolved to need Oxygen to live. Other planets don't have as much Oxygen as we need to live. They have other gases that would kill us instantly. That is why we need spacesuits to be able to walk on the moon and other planets. The same goes for Outer Space. Outer Space has no Oxygen at all.
