This thread is for the sole purpose of posting photos of confirmed sexed snakes. *Do not post guesses*



Keep this thread free of comments or chat.
Quality, focused photos, only.
Confirmation of sex should have come from personal observation of at least one of the following:
Probing, birthing or mating with visual confirmation of copulation.
All secondhand information is unacceptable.
With your photo include the following information:Species and/or subspecies, Sex.
Optional data could include.Age, length, weight.

This thread can become the benchmark for sexing Thamnophis. Firsthand confirmation is paramount to its integrity.

don't pay attention to the lump on the left side of her...that's a scar from getting hit with a shovel (I rescued her, accidently hit)

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 (https://www.facebook.com/Northumbriagartersnakes?directed_target_id=2343260 986)'s pics from facebook also make good reference so I combined them.

With all the births happening this may be a good time to post some sexing posts. ;) Please.
Please be sure to follow the guidelines in post #1

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
