Message: <blockquote data-quote="Josh's Frogs" data-source="post: 239641" data-attributes="member: 49228">Tarantulas are egg brooders. That means that the mother tarantulas stick around and tend to their eggsacs until they hatch. While they all defend their eggs from predators, some care for their eggsacs differently.  Most tarantulas lay out a silken mat. They lay their eggs onto this and then pull the silken mat up and around the eggs to form a sac. This sac is generally round. The m[ATTACH=full]76514[/ATTACH]other tarantula carries this and turns it, periodically, to keep the eggs on the bottom from being crushed by the weight of the eggsac. Other tarantulas choose, instead, to use silk to attach the sac to silk above and suspend the eggsac from above. Then they attach it on the sides to give it more support, keeping all of the weight of the eggs from being born by the ones developing at the bottom. Here we see an Usambura Orange Baboon Tarantula, having done so with her sac. She looks quite satisfied with her work in this picture.</blockquote>
