Harbor seal, the first class national protected animal, is popular for its cute appearance and called as “Bohai Sea’s Fairy”. Liaodong Bay area, located at the northernmost frozen area of China, is the southernmost breeding areas of harbor seal among other eight areas across the world. In every winter and spring, harbor seals migrate to Liaodong Bay to breed offspring on sea ice, while Liaoning is a “home” for them to stay during their journey.
