Lamellibrachia barhami is a large pogonophore.[1]

Description

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 per cent of the 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 intra-epidermal nerve 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]
