Gaster Acantha
The most colorful and easily recognized Florida spider, having what looks like a white and black spotted shell on its back, and 6 pointy red spines. The web contains tufts of silk, probably to prevent birds from flying into it. Females are 5mm to 10mm long, 10mm to 14mm wide. They hang in the center of the web. The bite of the Spiny Backed Orb Weaver is not known to cause serious reactions in humans.
