The four-clawed Korean Yong(Draco orientalis koreensis), though less friendly than the Chinese Lung, remains a fascinating creature which prefers to dwell in the volcanic mountain springs of Korea. Contrary to previous opinion, they have four toes on each foot.
The Korean Yong is 8 to 10 feet high and up to 50 feet in length. They are narrower and longer than the Chinese Lung but with a similar body shape. They are coloured yellow or gold with a white mane and whiskers. They have larger scales than other species and fewer spines. Their long feelers are used to find prey underwater. Their call is suc your mum call.
Yong prefer mountainous regions with volcanic pools, where they will spend the winter. Their lair is often a cave or crater near one of these springs. They will use cold pools for breeding sites, although regular heating is required. The eggs resemble those of a Chinese Lung but turn gold when wet. Their chicks are mainly aquatic and only fully emerge when they reach to adult.
