salt-fresh shark besides bull?

[mudchick]

I know the bull shark lives in salt water but is sometimes found in fresh or brackish tributaries and rivers. I thought I had heard of another species that does this but I'm not sure of my info. Does anyone know about another shark that can go from salt to fresh water environments?

Yep - theres a handful of very rare fresh-water sharks that live all their life in rivers. They are known from only a few specimens, belong to the genis Glyphis, include such beasties as the Ganges Shark and the Irrawaddy River Shark and can be read about here.

Several other salt water sharks head up rivers - theres info on which ones (43 species) and how they survive in fresh water here.

Cheers,
Rohan.

Glyphis are the usual suspects here. I understand there a couple of as yet undescribed species in this genus from the top end of australia and PNG. Freshwater rays are more common including some stunning amazonian and vietnamese species.

Still even more than I thought! Thanks for the info!

I think there is also a species of shark in Lake Nicaragua.

I think there is also a species of shark in Lake Nicaragua.

It was a somehow landlocked population of bull sharks (that I believe are now thought extinct due to pollution). Possibly some sawfish as well I think I remember reading.

"Tassie Rohans" post contains a couple of links to interesting information. The second one, I think, links to a reference to the Lake Nicaragua shark which apparently has been known to travel to and from the sea, via the river that connects the Lake to ?

Well that sux but I am not surprised. It was a way for the locals to make money. Regretably the lack of management created a problem. And I could not help notice the reference to that most powerful of aphrodisiacs .. fins. Cripes.
