This is what we lovingly refer to in these parts as a 'string of pearls' ... but actually it's a collection of spiderling cases. Once they hatch, each of these 'pearls' will release literally thousands of baby spiders. Not a happy thought for someone who is as afraid of spiders as I am. And there are zillions of these throughout the mangrove swamp. Wait 'til I show you a photo of the adults ... the arachnids in Florida are H-U-G-E.
