Spiny Back Orb Weaver

Gaster Acantha

Description:

Spiny orb-weavers is a common name for Gasteracantha, a genus of spiders. They are also commonly called Spiny-backed orb-weavers, due to the prominent spines on their abdomen. These spiders can reach sizes of up to 30mm in diameter (measured from spike to spike). Although their shell is shaped like a crab shell with spikes, it is not to be confused with a crab spider. -- http://en.wikipedia.org/wiki/Spiny_orb-w... Orb-weaver's bites are generally harmless to humans.

Thanks Emma! I see them all over our yard here in Florida. This guy's (or gal's) web was very low, attached to a couple of palmetto palms so I was able to get up close and personal with this one.
