freshwater bamboo shark

[rayman]

Hi Moontanman,

How many known species of shark inhabit freshwater? I've herd none but bullsharks and i've heard several. Are there more than bullsharks and what species are they. Even google isn't very good for this question.

You must ask the question right, then google is very good

Take a look at Table 2 on page 7 of the pdf.

For some reason I get nothing when I use that link. It tells me the file is damaged cannot be repaired.

Link works fine for me. I wonder what could be wrong?

The only thing i can add to this is the bullshark is an acception. They've been found as far north up the mississippi as Chicago. They'
ve also been found thousands of miles up the amazon. They would probably be found even more often imo if they could regulate their own body temp (like a Great White) ---which I think is the only shark known that can do that.. I actually caught a baby greatwhite (well, not me but my father) about 18 years ago off the coast of St. Pete.Actually we were around Egg Mont Key if anyone is familiar. So Weird things can happen..
I don't see anything wrong with this. If the fish do not seemed stressed out. Who is to say he can't handle it like the Bullshark can?? I dunno just my 2 cents

Hmm, I don't know, maybe it's my adobe file that is damaged and cannot be repaired?

Oh, btw as far as I know there has never been any indication of the bullsharks lifespan being decreased do to living in freshwater. .

mann i would love to buy one of those if it was actually a freshwater shark (which there is none) than just a slowly acclimated saltwater shark

There are a LOT of sharks/rays that can handle low salt levels at birth or for short periods. However, the claim of keeping this bamboo in 100% fresh is either a lie, or a short lived shark. Bamboos can't osmoregulate their body like bulls etc can. It will slowly shut down from the inside out and do irreversable damage to it.

Not to be difficult or to disagree with you, but he actually said that it wasnt completely freshwater. He said he keeps low levels of salinity in the tank. I dont know any of the biology but maybe there is enough salt in the tank that the shark can function but not enough salt to upset the systems of the goldfish .
