flvs... haha the answer is prop roots
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.
Red mangrove
It have 5.
Red Mangrove#) Growing along the edge of the shoreline where conditions are harshest, the red mangrove is easily distinguished from other species by tangled, reddish prop roots. These prop roots originate from the trunk with roots growing downward from the branches.#) This mangrove tree can grow to heights of over 80 feet (25 m), however, in Florida, red mangroves typically average 20 feet (6 m) in height#) Red mangroves occur from Cedar Key in the Gulf of Mexico and Daytona Beach in the Atlantic, southward through the Florida Keys.Black Mangrove#) The black mangrove, is characterized by long horizontal roots and root-like projections known as pneumatophores. It grows at elevations slightly higher than the red mangrove where tidal change exposes the roots to air. The pencil-shaped pneumatophores originate from underground horizontal roots projecting from the soil around the tree's trunk, providing oxygen to the underground and underwater root systems.#)Black mangrove reaches heights of over 65 feet (20 m) in some locations, however in Florida they are smaller with heights to 50 feet (15 m).#)Within Florida, they range from the Keys north to Cedar Key on the west coast and StAND MANY MORE DIFFERENCE
Breathing is the movement of air in and out of an organism to supply oxygen and expel carbon dioxide and water. This process is necessary for respiration which extracts energy from carbohydrates such as sugar. In plants, movement of air in and out of the organism usually occurs mainly via holes called stomata in the leaves. A good example of breathing roots occurs in mangroves where the roots are often covered by stagnant muddy water.
10 feet ACTUALLY the tallest white mangrove discovered is 64 feet! And WHITE mangroves are the smallest out of: Black Red Buttonwood
Mangrove trees [Rhizophora spp] tend to live in areas that are inundated daily by the ocean. They're able to survive in such environments by lower roots being submerged and serving as anchors and elevated roots being above water and taking in oxygen. They also are able to survive due to an internal pumping mechanism that removes excess salts from cells. Their most well known representative is the red mangrove [Rhizophora mangle]Their most common pest is a relative [Poecilips fallax] of the carver beetle. This beetle devastates the mangrove with large, long tunnels by which adults and larvae feed on the tree's seeds.

The Red Mangrove (Rhizophora mangle) produces fruits that sprout and mature while still on the parent tree. These are called viviparous propagules, which means "live birth". These eventually fall off and can float vertically in the water looking for a place to root (they appear somewhat like large pea pods with small roots sticking out of the bottom). They can withstand to float in salt water for over a year and survive on a dry beach up to two months.
the red mangrove lives in the mangroves in key largo, FL
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.
There are hundreds of species of mangrove. In Florida and the Keys the most common are the red mangrove, Rhizophoraceae, the Black mangrove, Acantacae, and the White mangrove or buttonwood, Combretaceae. Mangroves grow together along the coast lines. The whole group of them is called a Mangal. The Black mangrove grows furthest out in the water and has special breathing tubes. Then come the red mangroves and on higher land the White mangroves. Mangroves are very important for protecting the coast from erosion and creating new land
