This wasn't what you would usually find in a Starbucks parking lot. It went well beyond a tossed coffee cup and a few sugar packets.
Florida woman Shannon Moskoff witnessed something that was both disturbing and fascinating at a Boca Raton Starbucks: Mother Nature at work.
Moskoff, who says she was already contacted by entertainment show "Inside Edition," explained to her Facebook friends what went down during her morning coffee run: "I see this big branch. We stopped because it was moving. All of a sudden we see it's iguanas with the iguana's head inside the other iguana's mouth! We were amazed what was happening."

In the video she shot with an iPhone, you can hear Moskoff and her friend talking nervously about what the reptiles are doing behind the cafe.
"Are they fighting or sexing?" says one.
"Oh my God, they're eating each other," says the other. "I've never seen this."
They giggle, musing what the iguanas are up to: "Spring has sprung."
It's unclear why the two iguanas are engaged in this type of behavior, which does appear to be a duel.
Someone drove up behind Moskoff, she explains, so she couldn't see how the face-off ended, she says.
The Florida woman, who works in a dentist's office, says in another post that she is known as the "iguana lady" now.
