Marty’s photo of the day #3858: I took this photo on a dark, rainy night in Puerto Rico (that’s why there are a few water spots on the lens). I am standing at the entrance to a large cave that angles sharply down into the slippery rocks, trying not to fall in. What you are looking at is a Puerto Rican boa, attempting to snatch bats out of the air as they fly by. Yes, the boa was successful!
