What a cool lizard! Their main diet is ants, but they also eat spiders, beetles, termites, and grasshoppers. They are on the state list of species that are of special concern due to their declining population. Photo from shivathedestroyer on Inaturallist.org
This gorgeous snake is not venomous. They feed mostly on rodents. An interesting fact about them is that they are immune from the rattlesnake's venom! They are diurnal, but can on occasion also hunt at night. Hawks, coyotes, raccoons, opossums, and skunks prey on them. If found in your backyard, don't kill them. Please call animal control.

They love to eat spiders, centipedes, and termites. Males are more brightly colored than females. The whiptail is on the state list of species of concern because they have lost about 75% of their natural habitat. I took this photo near Poggi Creek, which feeds into the Otay River. Personal photo.
These turtles can be seen on the many ponds throughout the river valley. Males are a little bit smaller than females. They eat plants, crickets, crayfish, snails tadpoles. They don't have teeth, but instead have serrated, horny ridges on their jaws. Another interesting fact is that their gender is determined by temperature within the nest! They communicate through touch and vibrations. Photo by chrysaetos on Inaturalist.org.
They are small harmless snakes. These cuties like to hunt for worms, salamanders, slugs, insects and small frogs. We found this little guy on the fire road near Aquatica. Was about 8-9 inches long.
This snake does not have venom and is not dangerous to humans. They can get quite big (as much as 9 feet). We recently found a 6-footer in our back yard. They will do all sorts of things for defense such as crawling quickly away, freezing, striking to scare off, inflating its body, hissing loudly, and even shaking its tail to make a buzzing sound. They are a powerful constrictor. Such an important species to help control the rodent population! Photo from Erik22 on Inaturalist.org.
This cool lizard lives mostly underground. Unlike most lizards, this one can be active in the cold mornings. Photo from ccormier on Inaturalist.org.
This lizard preys on small bugs like ground beetles, grasshoppers and crickets. They can live up to 15 years! Photo from chrysaetos on Inaturalist.org.
What a beauty! They are highly venomous. With a thick body, it is a subspecies of the Western Rattlesnake. They prey on birds, small mammals, frogs, lizards, insects and even other snakes. I took this picture somewhere under the 125 bridge. It was saying "Don't mess with me!" Personal photo.
This snake is not dangerous to humans. It has toxins in the saliva which can be deadly on their prey. It is mostly an aquatic snake. It mostly eats fish, fish eggs, and tadpoles. Photo from jimmelli on Inaturalist.org.
These little guys love to bask on hot summers days along sidewalks, rocks and trails. They are so cute. I took this picture near my home. Personal photo.
