Area covered here is marked in red.

These are the native and well-established non-native herps that inhabit the Bay Area, which for our purposes includes the land surrounding most of the San Francisco Bay including parts of Alameda, Contra Costa, San Francisco, San Mateo, Santa Clara, Santa Cruz, Solano, Napa and Marin counties. In the East Bay, the range covered extends out to around Livermore, or before the mountains. As you go east into where the Coast Range meets the Central Valley, several new species occur which are not covered here.

Not every animal shown here is present in every part of the area covered here.

A large freshwater turtle with a massive head with huge hooked jaws, a long tail, a saw-toothed crest, and a shell that looks like it is too small to fit the body.
The legs are large with webbed toes and heavy claws.
The tail is longer than half the length of the carapace.

Average weight is around 45 lbs, but some captives have weighed in at over 75 lbs.

The skin is gray, black, yellow, or tan, with tubercles on the neck.
White flecks occur on some individuals.

The color of the shell ranges from black, brown, or olive to tan. The shell is often covered with mud or algae, which helps camouflage the turtle. The shell is heavily serrated on the rear edge, and scutes may have a pattern of radiating lines.

Active most of the year, becoming dormant in areas with cold winters, generally in late October.
Remains dormant either burrowed into the mud bottom, or under overhanging banks, root snags, stumps, brush, logs, or other debris.

Aquatic, found in or near water.
An excellent swimmer.

Sometimes seen basking on or under the surface in shallow water.
Often rests buried in the mud with its eyes and nostrils exposed in water shallow enough that it can raise its long neck up to allow the nostrils to break the surface and breathe without moving out of the mud.

Females crawl onto land, sometimes travelling over great distances, to dig a nest where they lay a clutch of eggs.
Egg laying takes place mostly in June and July (but can occur any time between May and October).
The eggs hatch in 9 - 18 weeks.
