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 (cf. genus Isoxya). 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. Orb-weavers' bites are generally harmless to humans.
Yes, that was the picture I meant. Do you think this one is the same? Even Gasteracantha cancriformis? What do you think, João??

It's the cancriformis itself, bayucca, they actually vary even in abdomen proportions instead of only the colors.
She was not in the soil, was in its web. It has rained a lot, the backyard is moist and dark, my uncle found more than 10 of these spiders webs. He took all the webs, because of its strange appearance, he fears that these spiders are poisonous. I took them with a stick and threw it away in the bush. I took this photo and another orange.
Actually I never have seen a Gasteracantha sp. on the ground. But from the shape I think it could be Gasteracantha sp. but most probably not the one from the link. Cancriformis is quite a variable species, most of them are yellow or white.
