Alaska Fish and Game wildlife biologist Jeff Selinger said snakes in Southcentral Alaska are not as far-fetched as one would think. The common garter snake is the only species of snake found in Alaska and can be found as far up as Northern Canada, he said. Selinger said no snakes have been recorded living in the wild in the Kenai Peninsula, but that does not mean people cannot have them as an indoor pet. Some pet stores sell garter snakes, he said. Another possibility that the snake arrived in Alaska via cargo ship, he said. “(Garter snakes) live off insects and frogs,” he said.
