    They are not just snakes. They're garter snakes.

    T. ordinoides. FEMALE 13 inches. Notice her thickness changes immediately after the vent. Tail is short. Indicates female. With ordinoides, females tend to have thick bodies (even when not gravid) while males are slim. Females also get much larger than males. Older adults near max size are easy to sex on first sight.



    Another T. sirtalis concinnus. MALE 26 inches. Vent at red arrow. Notice the thickness of the snake doesn't immediately change after the vent and his tail is very long. Indicates male. Females vent to tail tip distance is much shorter for a snake of the same size. Females tend to have broader heads than males. In the wild, the very large concinnus (38-42 inches) have always been female in my experience.

    Rod Hardman's pics from facebook also make good reference so I combined them.

    I might also suggest including scale counts, particularly of the subcaudals. Another useful measurement is the tail length. This can be expressed by percentage of total length.

    That should read "this is where the hemipenes are kept" There's two of them, remember? Funny... they only have one one working lung, but they have a backup when it come to reproduction. I guess we know where their priorities lie, huh? lol
