"River dolphins are the four living species of dolphin which reside in freshwater rivers and estuaries. River dolphins inhabit areas of Asia and South America. They are classed in the Platanistoidea superfamily of cetaceans. Three species live in fresh water rivers" (Wiki) - South Asian, Amazonian and Chinese. The latter or "Yangtze Dolphin" is now considered "functionally extinct" (Wiki)
The connection belongs to Ecology connections.
Do you know of another WHS we could connect to River Dolphins?
A connection should:
- Not be "self evident"
- Link at least 3 different sites
- Not duplicate or merely subdivide the "Category" assignment already identified on this site.
- Add some knowledge or insight (whether significant or trivial!) about WHS for the users of this site
- Be explained, with reference to a source
