Number of Eggs 75 to 1,000
Egg Incubation Period Approximately 6 to 9 weeks
Egg Sac Care Female tarantulas guard their egg sacs and may exhibit aggressive behavior if threatened.

It is important to note that male tarantulas have a significantly shorter lifespan compared to females. Male tarantulas usually die shortly after mating, while females can live for up to 20 years or longer. Female tarantulas also have the ability to molt multiple times throughout their lives, growing larger with each molt. These molting cycles allow them to repair damaged body parts and produce a new exoskeleton.

Overall, the mating and reproduction process of tarantulas is a fascinating aspect of their biology. It showcases the intricate behavior and life cycle of these captivating creatures.

Tarantulas in the Wild

Tarantulas are fascinating creatures that can be found in various habitats around the world. They play a crucial role in the wild as efficient pest controllers, keeping populations of small rodents, amphibians, and reptiles in check.
