A pearlfish spends the day inside the alimentary tract, or intestines of a sea cucumber. The fish emerges from the sea cucumber at night to feed on small crustaceans. The pearlfish gets a safe place to live. The sea cucumber does not gain anything from the relationship, nor is it harmed.

A cymothoid isopod lives inside the mouth of a snapper fish. The isopod severs blood vessels in the fish's tongue, causing the tongue to atrophy and degenerate. The isopod then hooks its pereopods, or legs, to the base of the fish's tongue, essentially replacing the tongue. The isopod stays there for the rest of its life, feeding on blood, mucus, and stray pieces of food from the fish.

The siboglinid tube worm, found at deep-sea hydrothermal vents and cold seeps, has no digestive tract. It relies on symbiotic bacteria that live in the tube worm's tissues. The bacteria oxidize hydrogen sulfide or methane for the worm.

Imperial shrimp attach themselves to sea cucumbers and get transported by their host to a large area of potential food with only a minimal expenditure of energy. They have been observed getting off their host cucumber to feed in productive areas and then getting back on for a ride to the next spot.
