Can you help identify this slug like creature?
Photo taken on Tormentos reef in Cozumel
hmmm, It doesn't look like any sea slug, sea hare, or nudi that I'm familiar with (and I'm not terribly familiar with them) the closest thing i found in this group was the nudi known as Caribbean Spanish Dancer.
But my first gut reaction to the pic is that this is most likely a Sea Cucumber of some kind, maybe a juvi.
