This is a Yellow Stingray (Urolophus jamaicensis), something I don't often see around Little Cayman.  Wesley found this one in a small cave at Coconut Walk and he waited very patiently while I got close enough for a decent shot.  These are very small rays, normally reaching a maximum of 15" across.

Here's another Yellow Stingray I found on the way back from Donna's Delight.  He was hiding under a big coral head.  I thought this photo was amusing because of the Soapfish hiding behind him.  I didn't even notice that until I looked at the photo later!
