Avicennia marina/Avicennia marina-mangrove (Avicennia marina)

There is white fluff on the back of the leaves. Don't underestimate this fluff. It is a "waterproof jacket" that acts as an isolation layer when it is submerged in sea water. Although its flowers are small, the orange flowers often bloom in clusters on the top branches and are very conspicuous.

Mangroves have the functions of blocking mud, preventing tides, and berms in the estuary/intertidal area. They also provide activity space for fish (mudskippers, soda fish), shrimps, fiddler crabs, birds and other animals and plankton.

Not only that, it is planted by enthusiasts in amphibious tanks and small sea tanks, which can effectively reduce the nitrogen and phosphorus content in the water in the breeding tank and achieve the effect of purifying water quality.

Many people think that mangroves can only live in seawater, but this is not the case. Freshwater is no problem either. Yes, in nature, mangroves can only be found in seawater, but mangroves can be grown in fresh water, even soft water (PH < 7). They are far tougher than we think.
