Porty Goes To Cayo Costa

Yesterday we dinghied to Cayo Costa via Murdock Bayou. We paddled when it got too shallow through the mangroves which led us out to the Gulf side beach. The shells are gorgeous; and I have been gathering many. When we returned to Kismet, Jim got out the fishing pole (which has only been out a couple of times!); and caught our first fish! Since we weren't prepared for the next step; cooking it; we threw it back. If anyone can identify what kind it is; let us know!
