There are almost 1600 pictures about Thamnophis on this site

Currently there are 35 species of the genus Thamnophis known. They occur from southern Canada through the United States, even in Central America (Honduras/Costa Rica).
Many of these species are popular as “pets” because of their beautiful colors, their sizes and, for snakes, large activity in the terrarium.
This website is meant as a guideline for the care of garter snakes. I will give a lot of general information, but also tell how I personally, already for decades, care for my snakes.
