Algae (esp. Halimeda sp.) and detritus

Quick Fact
Pineapple Cucumbers are known to host pearlfish, symbiotic fish that live in the cucumber's gut.  Pearlfish have long, slender bodies and are able to enter and exit their cucumber home through the cucumber's anus.  It is thought that they may feed on parts of the cucumber's digestive tract, as well as hunt for small crustaceans and fish outside the cucumber.
