Female Wolf Spider With Babies On Her Back

Charmaine rescued her from the swimming pool this morning, put her in a little plastic container with a bit of water in order for me to get as good a pic as possible! I must admit, I didn't know why she had such a lot of 'hives' on her back, until we saw them moving, ontly then did we realise it was a zillions of babies!
