Female with cylindrical or sausage-shaped trunk with a proboscis that may be either truncate or bifid; gonoducts usually single or paired; ventral setae usually either two or absent; anal vesicles usually branched. Male minute, parasitic in or on the female.	en	Biseswar, Ramlall (2012): Zoogeography of the echiuran fauna of the East Pacific Ocean (Phylum: Echiura).

03C187C0FFFB2541FF55F8F0EACAFC9C.taxon	description	Description. Female. Proboscis truncate; two gonoducts each with a basal gonostome. The two gonoducts open into a common duct with a single pore. Anal vesicles broom-like, with a great number of separate branches. Ventral setae may or may not be present.	en	Biseswar, Ramlall (2012): Zoogeography of the echiuran fauna of the East Pacific Ocean (Phylum: Echiura). Zootaxa 3479: 69-76, DOI: 10.5281/zenodo.282351
03C187C0FFFB2541FF55F8F0EACAFC9C.taxon	description	Description. Female. Proboscis up to 11 mm long, with small lobe at anterior end. Trunk 49 – 75 mm long, brown in colour and opaque. Ventral setae absent. Gonoducts one pair, opening into common duct with single genital pore; gonostomes basal in position. Anal vesicles tubular sacs covered with many long tubules. Genus Prometor Fisher, 1948 Description. Female. Proboscis long, ribbon-like, not bifid but truncate, the lateral margins fusing at the base to form a funnel that leads to the mouth. Two ventral setae. Gonoducts one pair with a specialized basal portion into which the large fan-shaped, bilabiate gonostome opens; a single common genital pore. Anal vesicles unbranched sacs with a large number of excretory tubules with apical ciliated funnels.	en	Biseswar, Ramlall (2012): Zoogeography of the echiuran fauna of the East Pacific Ocean (Phylum: Echiura).

03C187C0FFFA2546FF55F885EB9FFE4C.taxon	description	Description. Echiurans without sexual dimorphism. Proboscis well developed but never bifid. Trunk sausageshaped, usually covered with papillae. Longitudinal muscles in some genera thickened to form bands and oblique musculature between longitudinal muscle bands may or may not form bundles. Gonoducts paired, usually 1 – 3 pairs. Gonostome basal in position except in one genus and gonostomal lips may be fan or leaf-like, elongate and spirally coiled. A pair of ventral setae present in all genera (except in one species where numerous spinelets present instead). Interbasal muscle between setae may or may not be present. Anal setae and post-pharyngeal diaphragm present only in Echiurus. Dorsal and neuro-intestinal vessels usually connected by intestinal ring sinus at posterior end of foregut. Anal vesicles usually elongated, blind-ending tubes or sac-like but never branched; their surface usually covered with small, ciliated funnels.	en	Biseswar, Ramlall (2012): Zoogeography of the echiuran fauna of the East Pacific Ocean (Phylum: Echiura).

03C187C0FFFA2541FF55FBA7EC36F9F1.taxon	description	Description. Proboscis very much reduced. Distal part of mid-gut greatly enlarged and acts as a respiratory chamber, water entering and leaving it through the anus. Foregut very long and contains a gizzard. No sexual dimorphism.	en	Biseswar, Ramlall (2012): Zoogeography of the echiuran fauna of the East Pacific Ocean (Phylum: Echiura). Zootaxa 3479: 69-76, DOI: 10.5281/zenodo.282351
03C187C0FFFA2541FF55FBA7EC36F9F1.taxon	description	Description. Longitudinal musculature of the body wall lies between an outermost layer of circular and innermost layer of oblique muscles which are fasciculated. Two ventral setae connected by a strong interbasal muscle and one circle of curved anal setae. Internally, paired dorso-ventral muscles present anterior to the setae. Blood vascular system is absent. Two to three pairs of gonoducts with gonostomal lips that are long and spirally coiled. Anus eccentrically placed in relation to posterior ring of setae. Anal vesicles are large sacs. Sexes are separate.	en	Biseswar, Ramlall (2012): Zoogeography of the echiuran fauna of the East Pacific Ocean (Phylum: Echiura). Zootaxa 3479: 69-76, DOI: 10.5281/zenodo.282351
03C187C0FFFD2546FF55FE09EAE6FD95.taxon	description	Description. Two rings of setae surround the posterior or anal region of the trunk. A post-pharyngeal diaphragm almost divides the coelom into two parts. Gonostomal lips not spirally coiled.	en	Biseswar, Ramlall (2012): Zoogeography of the echiuran fauna of the East Pacific Ocean (Phylum: Echiura). Zootaxa 3479: 69-76, DOI: 10.5281/zenodo.282351
