Can frogs live in salt water?

Most species of frogs can not live in saltwater for an extended period. The Crab-eating frog is one of the only species of frog that lives in saltwater.

This Asian frog doesn't expel ammonia as other frogs do. Instead, Crab-eating frogs store urea, and this raises the amount of ions in their bodies. This limits how much water exits their skin, and allows them to live in saltwater without becoming dehydrated. Most frogs dehydrate very quickly in saltwater and die within a short period. Other species of frog that can survive in saltwater include African clawed frogs and southern leopard frogs. The best environment for frogs is fresh water, wetlands or dry land.
