Nudibranch Body Parts
Click on the images on the left to find out more about the body parts labeled in blue, or look below to read about the eyes and oral tentacles of nubidbranchs.
Eyes
Eyes of sea slugs are located below the tissue of the animal, so they cannot see actual images but only take a measure of light intensity. They are located near the brain.

Oral tentacles
These are used to help the slug feel it's way over the terrain, but they may also have some chemoreceptory functions. Oral tentacles are especially prominent in the Flabellinidae.
