No mouth, eyes, no digestive system

Among the deep-sea creatures, the most noticeable are clusters of red-crowned worms, 2 to 3 meters long, whose white coats are fixed to rocks. Neither mouth nor eyes, no digestive system, relying on the body protruding from the top of the cannula to filter the food in the sea water. Their blood is extraordinarily bright and filled with iron-containing hemoglobin.
