Lettuce Sea Slug at Pinel Island
Below are some photos and video of a lettuce sea slug (Elysia crispata) that we found while Extreme Shallow Snorkeling near the pier on Pinel Island. These are a common sea slug in the Caribbean, but they are not commonly seen because they are very small and well camouflaged. The skin frills on the sea slug’s back increase the surface area to increase oxygen absorption from the water.
