„Smiling Angel“ is the name of the young Chinese river dolphin swimming here with its mother. Unfortunately, not in the Yangzi River, where this species actually belongs, but in the Wuhan Hydrological Institute. The mother was brought here from Lake Poyang 14 years ago because the dolphins’ survival in their actual habitat was in danger due to environmental changes. She is the first female river dolphin to give birth to a cub in captivity.
