A female spider can lay up to 3000 eggs. Many species then protect the eggs with a silk bag, which they then fasten to the spider web for the mother to protect them. Once the eggs hatch, spider offspring come out, which look like smaller versions of adults. Finally, they leave the web to become adult spiders and repeat the process. This educational figure set helps kids know the spider's life cycle from egg to egg bag, spider pups and adult spider. Designed with scientific precision and great detail, this set is a great didactic tool to get to know arachnids better. The life cycle of a spider is part of the Safariology collection.
