San Francisco garter snake Thanopolis sirlalis tretraenia The San Francisco garter snake has greenish yellow stripes on its back, red and black stripes on its sides and has a greenish blue belly. It can be anywhere from 1.5 to 3 feet long. It lives near water, in wet, grassy meadows, marshes and ditches. The snake hibernates in something like a burrow. It eats fish, toads, frogs, tadpoles, salamanders, birds, small mammals, worms, slugs and leeches. It can lay up to 100 eggs, but only 16 babies will be bore each year. The snake was put up on the endangered species list on March 11, 1967. It is endangered because of water pollution caused by factories being built. Other reasons are more houses being built, reducing the habitat. There are also people who try to keep them as pets. Others are trying to save their habitats. Resources: 1.
