One species is critically endangered while the other two are vulnerable because they have small such small habitats (rivers and tidal rivers), and were thought to be extinct until ~2000.
Along with that (according to wikipedia), Glyphis gangeticus is thought to be critically endangered because they're in the Ganges and that area could account for up to 9% of global shark/ray landings. They were tought to be extinct AGAIN from 2006-2016 until one was seen in a market.
Pollution, overfishing, and a lack of knowledge (both by researchers and the public) are also contributing to their vulnerability. We literally don't even know how big they are, we only have estimates. They're often mistaken for bull sharks too.
Today I learned there are true freshwater sharks (genus Glyphis).
