When the sea slug eats, it absorbs and displays its prey’s pigment—the substance that gives the prey its color. The nudibranch absorbs the algae's chloroplasts (zooxanthellae) into the cerata, which acquire nutrients by photosynthesis using the sun to sustain the nudibranch for months.

Dorid nudibranchs, like the Limacia cockerelli, breathe through gills that are on their posterior (back) end. They have very few predators, which are mainly turtles, crabs, humans* and other nudibranchs. Scientists study nudibranchs because of their complex chemical makeup and adaptations. Scientists who study learning and memory use nudibranchs' large, simple neurons in their research. Some species are transparent and/or bio-luminescent, like the Phylliroe. Nudibranchs exploit .
