The salamander family includes tiny ones, from the pygmy salmander at 1.1" to the Chinese Giant, also claimed by Japan, at 5' 9" and 143 lbs. Imagine the size of its tadpoles! I have seen the ones that live in Ozark streams, which the locals call hellbenders. They are large enough to be scary when you pull one up.
This diverse group includes those with four legs, only two legs or no legs---the caecilians, sometimes mistaken for worms. They may be terrestrial or aquatic, and one California salamander climbs trees and uses its tail to help propel it. They have amazing powers of regeneration, able to replace a tail, part of a limb or an entire limb, leading to some gruesome laboratory experiments, all in the name of science.
In searching for this cache, you may see a common salamander called a newt. Or maybe not. Take a stroll through the woods, cross a wooden walkway and start up the hill. You needn't go very far.
Lots of parking available at the park.
