This list of mythical creatures that begin with this letter and I am constantly gathering information from each continent, and is continually being updated.
Fucanglong (Chinese)
In Chinese mythology, the Fuzanglong is the Chinese dragon of hidden treasures and an underworld dragon which guards buried treasure, both natural and man-made. Volcanoes are said to form when these dragons burst out of the ground to report to heaven. Several tiles and light reliefs depict Fuzanglong dragons serving as mounts to Immortals. The Fuzanglong possesses a magic pearl which is its most treasured possession.
Chinese dragons are usually depicted in five different colors. The yellow dragon, for instance, is believed to have power and is associated with good fortune. The red dragon, on the other hand, is said to bring good luck and happiness. Fuzanglong was a dark red like molten lava colour and this is said to symbolise the volcanic eruptions that he was associated with.
