Sea slug
On our morning dive, we encountered a lettuce sea slug. It was less than an inch long, in about 10 feet of water. Their color helps them blend in with algae, which they eat. Sea slugs absorb oxygen through their skin. The ruffles on the back provide more surface area for oxygen absorption. The head end can be recognized by the pair of tentacles that look something like rolled paper.
