Snakes Lizards Turtles Frogs Salamanders

This section attempts to serve as a very simple visual guide to aid you in the identification of herps that you might encounter in California.

Although this site was not intended to be an identification guide, most of the email I get asks me to identify an animal that a reader saw or found in their house or yard. As we continue to build new houses in former open space that once served as reptile and amphibian habitat, these encounters will continue to increase.
Since most of the requests I have received have come from the Bay Area and Coastal Southern California, where most of the population in the state resides, I have made illustrated lists of the herps in these regions in order to help you narrow down the species to consider in your identification process. The Bay Area page is here. The Coastal Southern California page is here.

This is not intended to be an exact and thorough key, just a very basic guide for those who know little or nothing about reptiles and amphibians, who have had a good look at the size, shape, color, pattern, habitat, and behavior of an animal. Even if it does not help you make a positive identification, this guide should at least help steer you in the right direction. Please feel free to continue sending me email with your questions and observations.



How to identify an animal using this guide

Determine if your animal is a reptile or amphibian, then determine what type of reptile or amphibian you are attempting to identify - a snake, lizard, turtle, frog, or salamander, using the information and pictures below.

After you know the type of reptile or amphibian, click on the name heading (snakes, lizards, etc.) and you will view a page with pictures grouped by pattern or appearance or other characteristics. Read the brief descriptions and look for a picture of an animal that resembles yours. When you find the animal, click on the name to view more pictures, information, and a map showing where the animal occurs in California. The maps are general representations of where various animals occur in the state and they can quickly help you determine if an animal occurs in your area.



Identification Problems

You may find identification of an animal difficult if it does not look exactly like those shown here, or if its behavior or surroundings do match our brief description. Keep in mind the following:

  • The descriptions and information here are simplified, and we do not yet have pictures of every size, age, and color phase of every animal.

  • Juveniles and newborns frequently do not look exactly like adults.


  • It is possible, but rare, that an animal has been released or has escaped captivity and therefore does not appear in this guide because it is not a California native.


  • An animal might have abnormal markings or appearance such as albinism (white and pink coloring), or melanistic (very dark coloring) and will not be shown here.


  • Many lizards change color depending on temperature, or will change color during the breeding season.


  • Some species have more than one color or pattern, which may not all be represented here. For example, some snakes and lizards will be colored to match their environment; dark animals are often found near dark lava rocks


  • Reptiles will appear cloudy or milky with dull coloring and a bluish haze over the eyes when they are about to shed their skin.


  • Lizards and salamanders can lose their tails, which may change their shape and appearance compared to our examples.


  • Some salamanders change their appearance during the breeding season when they return to live in water.


  • Reptiles and amphibians are sometimes found outside of their typical habitat or normal activity period. The brief descriptions used here represent only the most likely times and places where an animal is most often seen.


  • Often it is not easy to get a good look at a reptile or amphibian, especially if it is moving quickly, and then hides out of sight. The size, shape, pattern, and even the color of an animal in motion will appear different from the same animal when it is stationary (as in our photos.) Your description of what you think you saw may not be entirely accurate.



Not all of the species pages on this site have descriptions yet. If you are having difficulty using this guide to identify an animal, it will help to consult a good field guide such as the Peterson Field Guide: Western Reptiles and Amphibians 3rd Edition, by Robert C. Stebbins, ©2003 Houghton Mifflin Company.

Reptiles

Snakes



Snakes have long bodies with no legs. They crawl on their bellies. Some are excellent climbers, most can swim.

The body is covered with dry skin with visible scales, which may be smooth or rough, and might appear wet or slimy.

Snakes can be found on land, in water, in trees and shrubs, underneath objects, and in holes in the ground.

They can be active at any time during the day or night, but many species are mostly either diurnal or nocturnal.

Snakes can be seen whenever there is warm weather. Rarely in winter.

Lizards



Lizards have four legs and a tail. An exception is the legless lizard which has no legs, and looks like a snake.
Also, some lizards may have no tail because it has come off.

The skin of a lizard is dry and covered with scales.

The majority of lizards are active during daylight. Exceptions are geckos and some night lizards which are active at night.

Lizards are typically seen actively moving about in daylight, or sitting still in the sun. They are also found hiding underneath objects and debris, usually in sunny areas. Exceptions are skinks and some alligator and legless lizards, which prefer more moist environments.

Lizards can be seen whenever there is warm weather, including occasionally in the winter, especially in the south.

Salamanders can be mistaken for lizards, as they have four legs, a tail, and a similar body pattern, but they will have smooth, moist skin, and generally they are found hiding underneath something in a moist and usually shady area, usually during cool wet weather.

Turtles



Turtles are distinct from all other reptiles (and amphibians) in California, due to their large, rounded shell.

Turtles are almost always found in or near water, often basking on branches or logs in the water. The Desert Tortoise, however, is found on land in the desert, usually far from water. Seaturtles will be found in the open ocean, or on a beach, but they are rarely seen in California.

Most turtles are active during daylight during warm weather, including sunny winter days.



Amphibians

Most amphibians have moist, smooth skin and are usually found in wet environments, moving during rainfall, and in or near standing or flowing water. Exceptions are toads and newts, which can have rough or bumpy skin. And sometimes you will find amphibians in dry areas, such as on roads at night, and even in deserts with no obvious water nearby, either feeding, or moving between wet areas.



Frogs and Toads



Frogs and toads have four legs, with enlarged rear legs, and no tail. An exception is the male Tailed Frog, which appears to have a short tail, which is really a reproductive organ.

They can be found during the day or at night, in water, and on land, including climbing in bushes and trees and on roads at night. Looking around ponds on warm sunny days is an excellent way to find frogs.

Frogs are not usually confused with any other type of reptile or amphibian, but frog larvae, or tadpoles, can be difficult to tell apart from salamander larvae. Their identification is not covered here.

Salamanders



Salamanders are secretive and rarely encountered. Most of us are unaware of their presence, even though they may be abundant.

They have smooth, moist skin, and a tail, although the tail may be completely or partially broken off.
Exceptions are newts, which have bumpy, dry skin, when they are in their land phase.

Salamanders are usually active at night, and rarely seen, unless they are found hiding beneath objects. Exceptions are newts, which are active day and night, and a few other air-breathing salamanders which which can be seen migrating to breeding ponds at night, or swimming in the ponds during daylight.

Salamanders can be found on land, in trees, underneath objects and bark, on rocks and walls, including vertical rock faces, in streams, in ponds, and in residential yards and basements. Salamanders are generally active beginning with the onset of the fall rains, which sometimes stimulates much movement, until the ground dries up in late spring or summer. During very cold periods in winter, they may be inactive. At higher elevations, they are active in summer.

Salamanders may be confused with lizards, due to similar body shapes, but lizards have dry skin with visible scales and are generally observed during daylight.

Young Salamander larvae can be difficult to tell apart from frog tadpoles. Older larvae have gills and legs and long thin bodies which differ from tadpoles. The identification of larvae is not covered here.
