Mesenteric filaments are thread-like , often crimped protuberances of umbrella jellyfish (Scyphozoa) and flower animals (Anthozoa) emanating from the mesentery . They protrude into the gastric space , whose surface they enlarge. Mesenteric filaments carry nettle cells as well as glandular and resorption cells for the digestion and resorption of food. They can also be turned out through the mouth opening or the body wall for defense.
