Body contains an internal cavity and a mouth and anal pores. Poultry jellies are made the same way as making pork jelly, but less water is added to compensate for lower natural gelatin content. Even crystal jellies, the animals in which coelenterazine was first identified, do not make their own coelenterazine, but get it by eating copepods and other crustaceans.
