Question:
Why do frogs have to keep their skin slimy?
Replies:
Frogs are amphibians. All amphibians have to stay either in water or where
they will not dry out. Those that spend most of their time out of water
have a
skin coating to keep them from drying out. Some feel "slimy" while others
feel dry. Those that spend most of their time in water have a protective
skin coating, much like many fish.
