The roots will quickly form and take hold in sand substrate or in live rock. So, to survive, they must create freshwater from seawater. Mangroves are viviparous (bringing forth live young), just like most mammals. The fertilised seed develops into a seedling while still attached to the flower. Mangroves trees that grow in coastal regions in tropical geographies. They do this in one of three ways: by filtering out most of the salt, as they draw seawater into their roots; by excreting salt through glands in their leaves; or by extracting and storing salt in older leaves or bark, which they duly shed.

The leaves are 5 to 15 cm (2 to 6 inches) long, opposite, oval or elliptic, and smooth-edged; they are thick, have leathery surfaces, and are borne on short stems. Rather than producing dormant resting seeds like most flowering plants, mangroves disperse propagules via water with varying degrees of vivipary or embryonic development while the propagule is attached to the parent tree. That's because twice a day seawater comes in and floods this whole area. Their special adaptations to survive in salt water allow these plants to live in a habitat only a few species of flowering plants can. The seedling is merely a long, cigar shaped 'stem' (called a propagule ) and this grows for up to a year on the tree before it is ready to find a place of its own to grow. Introducing mangroves to an aquarium is normally done by way of the seeds, which look like long pods that are fat at the bottom (root area) and skinny at the top (leaf-growing area).

As climate change threatens to increase the frequency and severity of storms, mangroves provide a stout defense Because mangroves live in the sea, they have special adapted roots that conserve water and leaves that are thick and waxy to help prevent water loss. This is because ocean water is full of salt. In fact, there’s a case to be made that mangroves are the most useful ecosystem on Earth. Each kind of mangrove is uniquely suited to its ecological niche, and the wrong kind in the wrong place won’t survive. The common mangrove grows to about 9 metres (30 feet) tall.
