Great pics as usual. I especially liked the fireworm and the jellyfish with the fish associated. As to the unidentified eel, at first glance it looks like some type of snake eel, which is in a totally different group than moray eels. However, I'm at work and don't have my reference books that I can consult. I will look this up later at home. I'm not even sure if snake eels are found nearshore in the Gulf of Mexico. In a quick search on-line, I found this pic of something called a "king snake eel" from an offshore fish survey in the Gulf of Mexico:

Cursor down through the photos to see the snake eel. The head in the photo looks a little like the head in your photo. Snake eels live in burrows in the sand and often have their head sticking out. I've seen them out swimming along the bottom in the Caribbean. Morays live more in rocky areas.
