No, just the pointy spines on an agave! But, don't they look like dragon's teeth? I just love these! I found these on my morning walk at the Marriott Desert Ridge villas. There were quail, cottontails, doves, and cactus wrens out and about at dawn this morning. It was a nice walk then. I went out again about 8:00 a.m. and it was so hot and sticky and HUMID that I came back to our room completely soaked with perspiration!!! Sunday Stills Challenge for August 14, 2011.
