Spiderlings

As the eggs hatch, the spiderlings usually disperse by ballooning with wind currents. The mother takes care of the young ones until they grow up and are able to find food for themselves. They capture prey items by snaring them in sticky webs, and when stuck, they paralyzing them with venom injected through the fangs.
