How to tell if tarantula is male or female
Spermathecae: the female's internal marker
For females, the presence of spermathecae is the definitive sign. I mean, these are paired sacs located within the abdomen that store sperm received from the male during mating. The most common way to check for spermathecae is through a technique called "vent sexing" or "molt sexing." Vent sexing involves carefully flipping the tarantula (which can be stressful and risky for both the keeper and the tarantula) to examine the underside of the abdomen. Females will have a distinct ridge or line where the spermathecae are located, whereas males will have a smooth abdomen. A much safer and often more reliable method is molt sexing. When a tarantula molts, it sheds its exoskeleton completely. The exuvia (shed skin) can be examined under magnification. actually, the area between the book lungs on the underside of the abdomen will reveal the presence of spermathecae in females. look, a smooth, unbroken surface in this area indicates a male. This method is highly accurate and poses no direct risk to the live tarantula.
Morphological differences: embarking of sexing
The most definitive ways to sex a tarantula involve examining specific morphological characteristics. These are physical traits that differ between males and females and are often only apparent once the tarantula reaches a certain maturity, typically post-puberty (around 2-3 years old for many species, but this varies widely). It's important to note that some species are sexually dimorphic, meaning males and females look noticeably different in color and pattern even before reaching maturity, but for many, the primary sexing methods are based on mature characteristics, right?
Frequently asked questions
When can I reliably sex my tarantula?
You can typically sex tarantulas reliably once they reach maturity, which varies by species but is often around 2-3 years old, right? Pre-pubescent tarantulas are very difficult to sex accurately.
let's be real, is it safe to sex my tarantula?
Sexing a tarantula can be stressful for the animal. Molt sexing is the safest method as it doesn't require handling the live tarantula. Vent sexing requires careful handling and should only be attempted by experienced keepers.
kind of, can I sex a tarantula by its size?
No, size is not a reliable indicator of sex in tarantulas. Both males and females can grow to similar sizes within a species, although there can be some general trends in average size between the sexes in certain species.
