About this photo:

During a night walk at Chan Chich, Jim tried out his new "spider light," a small but bright headlamp. Wearing it on your head means that the light from spider's eyes is reflected back to your eyes. That makes it easy to see the spider's "eye shine," an eerie green, and locate the spiders. We were astonished by the number of Wolf Spiders we saw on this night walk. It was easy to count 8-10 from one spot, then move a few feet and see 8-10 more. The woods are full of these guys.
