    Grey mangrove (Avicennia marina)

    Grey mangrove is the most common and widespread mangrove found within intertidal zones across Australia, and throughout the world. Growing to a height of 3-10m, they thrive best in estuaries with a mix of fresh and salt water. They excrete excess salt through their long thick leaves, and absorb oxygen through their aerial root system.
