Can Frogs Live in Saltwater Environments?
Frogs generally cannot handle living in saltwater environments. If they for any reason are put into saltwater, they usually die within a couple hours or so. The salinity in frogs’ blood and cells isn’t as densely packed as it is in saltwater.
If a frog lived in saltwater, the water would quickly spread over them. This, in turn, would invite dehydration. The danger of dehydration would also combine with another serious problem — salt distributing all throughout the frog’s insides to a poisonous degree.
Because of these factors, saltwater is a big no-no for the vast majority of frogs in existence. Apart from the crab-eating frog, African clawed frog and southern leopard frog, frogs in general cannot survive life in saltwater — or even close to it. Most frogs have to stay in fresh water.
