Question

Do any frogs live in salty waters?

Answer 1

Only three are known to live in salty waters. All others would become dehydrated and die.

Crab-eating frogs differ from the bulk of frogs in that their bodies don't expel ammonia. Their bodies store the chemical compound urea, which raises their density of ions. This storage then minimizes how much H20 exits their skin. This stops crab-eating frogs from experiencing dehydration in saltwater.

A couple other types of frogs can also occasionally manage in brackish settings, including both African clawed frogs and southern leopard frogs.
