The Yangtze finless porpoise is declining in population. Attempts to save them include a ban on fishing in the river.
One porpoise, born in 2020 in captivity, is a ray of hope. That's because it is the first second-generation Yangtze finless porpoise that was born through an artificial breeding programme in Wuhan.
For International Freshwater Dolphin Day, there was a contest to name the porpoise. The winning name was Hanbao, a mash-up of words that could mean "little baby" or "treasure" while winking at its birthplace of Wuhan.
Scientists say breeding porpoises in captivity is valuable because it "enhances our understanding of the life habits of the porpoises."
