Their root systems have evolved to literally filter out the salt before absorption.
there is an excellent explanation at http://www.floridaoceanographic.org/environ/mangrove1.htm
mangroves have stilt roots. mangroves grow in soil which is clayey and covered with salty water. stilt roots support the stem and take in air directly from the surroundings.
Pencil roots are roots mostly found in mangroves. They allow the plant to absorb water during both high tides and low tides.
Mangroves have special features which protect them from salt. Some mangroves are able to filter most of the salt out as they take water in through their roots, some concentrate extra salt in old leaves (which turn yellow and die), and some are able to get rid of the salt through the pores on leaves or special glands. Mangroves can also grow in fresh water, but they have almost no competition in salt water because so few plants can grow there.Mangroves have special features which protect them from salt.

They allow the exchange of gas as the water below them is too muddy with almost no air. This would also prevent the roots from rotting. The mangrove roots are also known as "breathing roots", which implies its function, to breath.
Baldcypress is an example of a tree that breathes by its roots. The woody plant in question (Taxodium distichum) maintains buttress roots. Cypress "knees" permit airflow and anchorage in waterlogged environments.

Mangroves are not dogs. Mangroves are tropical trees that grow in brackish water.
The mangrove roots suck up the water thus the flooding is somewhat controlled by the mangroves. Hope it helps!
state were each mangroves are found in reference to the water

There are three species of mangrove trees: red mangroves, white mangroves and black mangroves. They all live in salty or brackish waters along the coastlines. Red mangrove are usually in the lower/deeper waters. They are the ones with the large prop-roots. Reds and Blacks live in higher edges of the wetland/shorelines.

1). is mangroves grow above water and corals don't 2). corals are very frigaile mangroves are strong
oxygen (air) and water
