[Note Guidelines] Photographer's Note
Common name : A Spiny Orb Weaver Spider, Gasteracantha cancriformis (Linnaeus) (Arachnida: Araneae: Araneidae)

Identification : This species can be easily distinguished from all other spiders in the tropics. Females may be 5 to nearly 9 mm in length, but 10 to 13 mm wide. They have six pointed abdominal projections frequently referred to as "spines." The carapace, legs, and venter are black, with some white spots on the underside of the abdomen. The dorsum of the abdomen is, typically for Florida specimens, white with black spots and red spines. Specimens from other areas may have the abdominal dorsum yellow instead of white, may have black spines instead of red, or may be almost entirely black dorsally and ventrally. Males are much smaller than females, 2 to 3 mm long, and slightly longer than wide. Color is similar to the female, except the abdomen is gray with white spots. The large abdominal spines are lacking, although there are four or five posterior small humps (Levi 1978, Muma 1971).

Photo : Just framed and resized the photo. Captured on a Canon SD400 - f/5.6 - 1/60 - 6mm focal length - no tripod - macro mode - with flash. I just got this Digital ELPH and took it for a spin. So far, I've been very pleased with the results. Hope you enjoyed the picture too.

Strange creature. Looks like from a SF movie.
Wellcome to TN, Kenneth.Good shot. Maybe the yellows are a bit overexposed. Also I think this photo desesve a larger size, for a better wiew. Anyway, overall, good job.

Regards, Petru
