The Chinese alligator, one of only two alligator species in the world, is covered by the Convention on International Trade in Endangered Species.
The Chinese alligator, locally known as ''tu long'' (earth dragon), is classified as ''critically endangered'' in the international Red List of Threatened Animals maintained by the World Conservation Union, or IUCN.
According to the Maruyama Zoo in the Hokkaido capital, five of the 20 eggs laid by a female Chinese Alligator in mid-May have been hatched in an artificial incubator.
The Chinese Alligator, or Alligator sinensis, is a small dark-gray alligator about 2 meters long which inhabits the Yangtze valley in China.
The success of this small population suggests that there's hope for bringing the Chinese alligator
back to some parts of its former distribution," he added.
These new islands and wetlands are potential environments for reintroducing the Chinese alligator
to the wild.
