Abstract
Previous literature on the external morphology of the Pogonophora describes the end of the body as ending in a blunt point. However, a definite structure, here referred to as the “anchor”, is present posterior to this point, delimited from the rest of the body by a narrow waist. The “anchor” consists of a bulbular structure followed by a vermiform region possessing 17 rings of 4 setae each, arranged in 4 longitudinal rows: dorsal, ventral, and lateral. The extremity of the animal is provided with a sucker. The “anchor” is believed to be the true metasoma of the adult.Keywords
