Mangroves grow in salty coastal water and filter salt out through special glands in their leaves.

The longer version

Living in tidal water means coping with salt that would damage most plant tissue. Mangroves deal with it at several points: many species block much of the salt at the roots, some store it in older leaves that later drop, and others pass it out through glands on the leaf surface.

Several species also prop themselves above the mud with arching roots or upright breathing roots, since waterlogged soil holds little oxygen. Seeds often begin growing while still attached to the parent, so the seedling is ready to take hold once it drops into the mud.
