How to recognize the Sex of her Snake

How Old walk a Snake need to Be come Tell that is Gender?

Some the the techniques we will talk about can be supplied from day among a snake’s life, and also how the breeder or pet save determines the sex that the snake before selling it.

Other techniques (mainly the ones based upon external appearance) call for that your snake get (or has practically reached) sex-related maturity.

Sexual maturity have the right to vary a little bit between different species but frequently falls right into the two-to-four-year-old range.

How to identify the Sex of her Snake

From optimal to bottom, we’ll begin from less reliable, beginner-friendly methods come surefire, expert-only ways of sexing a snake, or identify its gender.

Size and Appearance Differences, or sex-related Dimorphism

This technique will depend heavily on the species of her snake.

Not all varieties of snake display screen sexual dimorphism or significant size differences in between the genders. Friend will need to determine which details differences apply to males and which ones apply to females for your species, also in those the do. Additionally, sexual dimorphism commonly isn’t evident until the line reaches sexual maturity.

In ball pythons, females room slightly larger than males. In anacondas, females are about 4.7 times larger than males! Conversely, with rat snakes, males room typically approximately 14% larger than females.

Some vipers screen a connected trait dubbed sexual dichromatism, or different colors for males and also females. Europe adders are infamous for this trait, but there are various other species, as well.

Buyer’s Tip: once you have made decision on which species you space going to purchase, or if you already have her snake, carry out some an ext reading and also photo evaluations to find out if the type of line you own displays any sexual dimorphism.

Anal Spurs

Down appropriate freaky deformity or sneaky an enig weapon? Actually, anal spurs space neither. In truth, they’re the remnants of hind legs that specific varieties once had thousands the years earlier before development kicked in.

This technique of sexing a snake usually isn’t really reliable, yet it’s useful if you room only searching for an educated guess.

In countless python and also boa species, you will certainly see tiny “spurs” – bony remnants that the hind foot of your ancestors.

These look like rose thorns and are uncovered on your snake’s belly, on the right and left side of her snake’s cloaca.

In most species, the spurs on a male space much bigger and much more well-defined than a female’s spurs. Males will usage their spurs during combat with other males and aid grab top top the female throughout mating.

Note that, because spurs space the remnants of rear limbs, some snakes do NOT have visible spurs.

Only snakes the haven’t adjusted or evolved an extremely much still exhibition this piece of anatomy, like boas and pythons. Rat snakes and also other colubrids generally do not have actually them.

As aforementioned, this isn’t really reliable method…

A female might have huge spurs, or a male deserve to have small spurs. Just choose you and I, each snake’s human body composition is individual and unique.

If you are only searching for a marker so you deserve to stop calling your scaly pal “it” and start calling castle “he” or “she,” this is a great tool.

If you have actually your heart set on purchasing a male or woman for reproduction purposes, perform NOT depend on spur alone.

Unless disappointment’s your thing…

Tail Shape

To the trained eye, this an approach of sexing a snake deserve to be VERY reliable.

However, that takes years of practice and also dozens of line to to compare to consistently and successfully determine a snake’s gender based on tail shape, alone. If you only own one snake, or you very own two snake of the exact same gender, and this is your first attempt, you most likely will not be able to make any type of conclusions.

However, if you placed a male and a female line side-by-side, there is a definitive difference in the shape of your tails.

The reproductive guts of male dearteassociazione.orgs are referred to as hemipenes. Hemipenes room housed internally in the snake’s cloaca and also are essentially two penises.

Other types of, such as bearded dragons, likewise have hemipenes.

If you space looking in ~ a masculine snake’s tail, girlfriend may notification these features:

A longer size to accommodate the hemipenes.Thicker close to the cloaca, then unexpectedly tapers ~ 8+ subcaudal scale or 2-3″, depending on the full length of the snake.

On the various other hand, a female’s tail is typically:

Shorter in comparisonEvenly tapered indigenous cloaca come tail tip.


Popping is usually an ext successful when performed top top younger and smaller snakes.

Older, bigger snakes generally have sufficient muscle tone to hold their offal inside.

Too much pressure when popping have the right to injure a snake, for this reason it’s right to have actually someone with experience display you just how to do this technique in human at first.

Popping a snake is completed by applying firm however gentle push to her snake’s tail ~ above the ship side, about three-quarters the the way from the cloaca to the tail tip. Without releasing any of the force, you on slide your ignorance up the snake’s tail towards its cloaca.

In males, this have the right to push the hemipenes up and out of the vent. They will certainly pop out, looking favor two red tubes. Nothing will certainly come the end if it’s a female.

Again, I should reiterate the this an approach CAN be harmful if not done correctly.

You additionally run the threat of popping a “false female.” If the an approach is performed incorrectly and also there isn’t enough pressure, nothing will pop out, also if that is a male.
