[27] The California giant salamander can produce a bark or rattle, and a few species can squeak by contracting muscles in the ...

This secretion comes from large poison glands around the back and neck. The spotted salamander, like other salamanders, shows great regenerative abilities: if a predator manages to dismember a part of a leg, tail, or even parts of the brain, head, or organs, the salamander can grow back a new one, although this takes a massive amount of energy ...
[15] [16] The common mudpuppy never leaves its aquatic environment and therefore does not undergo morphogenesis; however, many salamanders do and develop differentiated teeth. [17] Aquatic salamander teeth are used to hinder escape of the prey from the salamander; they do not have a crushing function. [17] This aids the salamander when feeding.

Salamandridae is a family of salamanders consisting of true salamanders and newts.

Their skin is very granular because of the number of poison glands. They also lack nasolabial grooves.
