Some of the information was learned by reading books by Robert C. Stebbins. There are more than ten species of Batrachoseps in California with more being described as we go . B. attenuatus is the only one found in the greater San Francisco Bay Region. They never purposely enter water and young resemble adults but are smaller. The Slender Salamanders are non-migratory and the entire home range may be a patch roughly 12 feet in diameter.
Primary food is slugs.
Note the wormlike body with tiny legs . A newly hatched slender on a quarter . Sometimes found below large trees under surface objects, but the animals are more often in the trees themselves where egg laying and hatching, as well as overwintering of adults occurs. Good climbers, Arboreal Salamanders even have prehensile tails to help them move through non-horizontal spaces. See above, under California Slender Salamander.
