They produce woven masses of bent roots that are seen during low tides. Seeds from the mangroves are unusual because they mature while still on the tree, sprouting seedlings that can grow up to 12 inches long. The seedlings are cigar-shaped and heavier where the root end is located than at the leafy end. When the seed falls, they usually plant themselves below the parent tree. Red, white, and button mangroves grow in southern Florida and in other tropical areas.
Mangroves are home to many animals.
These include oysters, shrimp, barnacles, and small fish. They collect sand when water flows through and the sand gets caught in the roots. After many, many years an island forms from the sand that has been collected. I think mangroves are very interesting. It is how Key Biscayne began.
