Mangroves

No, I'm not talking about colonies where they grow men like in the matrix.

Mangroves are trees that grow in an area that goes up and down daily due to tide changes. So yeah, they live on salt water.

The interesting part is that their roots spread out everywhere and also grow upwards to get pockets of oxygen when the water is in, and so as you can see in this picture, when the tide is out you can see all the roots pointing out of the dirt. when I first saw them up close, they gave me the chills as it reminded me of an Indiana Jones movie.
