Class: Echiuroidea
Order:Echiurida
Family:Echiuridae

Description
Size: Total length 47-85 mm; proboscis 15-26 mm

Color: In the living condition the whole body is of deep reddish winous tinge, translucent, but not markedly so. The posterior extremity is somewhat paler than the remaining part. The proboscis is purplish pink while dendritic outgrowths are of bright red color.

The dendritic outgrowths of the proboscis margin are highly developed, having a gill-like appearance and are confined to the proximal third of the margin, the distal part of which is quite smooth. Longitudinal ridge of conspicuous nature is present on the proximal part of the ventral surface of the proboscis between the two rows of dendritic outgrowths. Ventral hooks are golden yellow in color and placed anterior to the nephridiopores. Papillae near the posterior end of the body are conical and have a tendency to be arranged in transverse rings.
