Its tentacular crown is formed of several, fused, horseshoe-shaped tentacle lamellae. The second segment has two body folds, near which open the genital ducts. The trunk, which comprises 89% of its total body length, is undifferentiated. The true metasoma is without setae. The heart is a simple muscular elaboration of the anterior end of the ventral blood vessel. The brain is large, and from it arises a pair of intraepidermalnerve cords, which extend the full length of the vestimental region; thereafter, they join and form the a nerve cord of the trunk. Associated with the brain and the nerve cords are the dorsal tubes.[1]
