Halocynthia roretzi

Halocynthia roretzi, otherwise known as the sea pineapple, is a fairly simple creature. It is an invertebrate that grows in warm, nutrient-rich waters. It is classified under the subphylum, Urochordata. This creature is sessile, meaning that it is permanently fixed to a surface. It commonly resides on pilings, ship hulls, sea rock, and on the backs of large crabs. It eats tiny creatures that it filters out of the water through their pharyngeal slits. It is relatively low in the food chain, as it has many predators.

Halocynthia roretzi is rarely found in open waters due to its vast amount of predators. However, many can be found off the far eastern coast of Asia and the coasts of South America. A number of Asian countries and South American countries grow and cultivate this organism and serve them as a dish in their native cuisines. These countries include Korea, Chile, and Japan.
