How long do axolotls and other salamanders live?

Salamanders have life spans varying by species. They live from 3 to 55 years. The axolotl’s life span is on the shorter side of this range.

What determines whether an axolotl will grow up to be male or female?

Axolotls have genetic sex-determination - a locus on an axolotl chromosome determines whether an axolotl is male or female.

In salamanders, the sex determining mechanism is referred to as ZZ/ZW and the heterogametic sex is female.
