Batrachoseps nigriventris, Black-bellied Slender Salamander
This little salamander lives under rotten boards, or logs and in the cracks in the soil.
Diet includes small bugs, larva, earthworms, slugs, aphids and other small prey.
You'll seldom see this little animal in the open unless it's a rainy day as they need cool moist conditions that rotting wood or decaying leaves afford. So you might find it as you're cleaning out a drainage pipe that was clogged with leaves and debris.
Eggs are commonly laid under rocks, boards or logs in moist shady spots. As adults they rarely move more than 1-2 meter(5 ft.) from where they were born.
They are eaten by skunks, raccoons, foxes, snakes, moles and numerous other animals.
