Can you tell the age of a tarantula by the size of its fangs?

Many people believe that you can determine the age of a tarantula by the size of its fangs, but this is actually a myth. The size of a tarantula's fangs is determined by its species and sex, not its age.

Tarantulas shed their exoskeletons (molting) to grow throughout their lives, but this does not always correspond to an increase in fang size. In fact, some species of tarantulas may have larger fangs as juveniles than as adults.

There are some methods that can be used to estimate the age of a tarantula, such as counting the number of molts it has gone through or looking at the size of its abdomen relative to its body. However, these methods are not always accurate and should be used with caution.
