Sexing A Tarantula By Molt. Male and Female

This guild is to keep it simple so hobbiest can accurately and easily find the informatio

n to check out their tarantulas sexual organs to determine sex

Female only have SPERMATHECAE

Males do not have SPERMATHECAE

The SPERMATHECAE is a flap like organ you can lift with a toothpick.

Males only at maturity have Palpal bulbs and Tibial Hooks

not all mature males get tibial hooks but all mature males get palpal bulbs so checking for hooks is only a secondary way to confirm mature males

Focus more on checking palpal bulbs as all mature male tarantulas get them

Palpal bulbs are also referred as "boxing gloves 🥊" in the hobby due to them looking like boxing gloves on the pedipalps of mature male tarantulas
