Are salamander a mammal?
No. Mammals are warm-blooded creatures with fur, skin or hair,
and they give birth to live young which they then feed with
mother's milk.
Like a mammal, a salamander is a vertebrate, but that is where
the similarities virtually end. A salamander has moist skin, and is
cold-blooded. It lays eggs and has to live in water for part of its
life. The salamander is a member of the amphibian family, like
frogs, toads, newts and axolotls.
