Answer to Question 1
Salamanders and newts make up the order Caudata, which includes those amphibians that have tails.
Salamander is a broad term and can be used to apply to all members of the order Caudata. Newt is a narrower
term used when referring to members of the order Caudata that remain primarily aquatic throughout
their lives.
Salamanders and newts have lizard-like bodies with a tail. Most have thin, moist skin, but those living in
dry areas have thicker, dryer skin.
Answer to Question 2
Newts are small, semiaquatic amphibians similar to salamanders. They spend a good part of their time in
water; they need moisture to keep their thin, soft skin from drying out. Newts are able to replace lost or
damaged parts of their bodies by regeneration and periodically shed their skin.
