Physical Description

Species Euclymene zonalis

As with other members of family Maldanidae (bamboo worms), this species has segments which are mostly longer than wide. The first setigers are clearly demarcated from each other. This individual has 15 setigers plus the prostomium/peristomium. It has a cephalic plate on the prostomium (photos). The cephalic plate has a conspicuous , leathery rim in which the lateral notches are not prominent (photos). Setiger 1 is clearly demarcated from the prostomium/peristomium and has several capillary notosetae and a few modified uncini for neurosetae . The neuropodia of the first 3-4 setigers have only a few setae, and these are modified uncini. Many of the segments have ringlike folds in the skin . The glandular rings around setigers 5 and after are not prominent. The last several segments all have setae. The anus is central on a funnel-like projection from the posterior end of the pygidium. The cirri around the pygidial funnel are all about the same length .[1]


This family is often found in tubes on sandy/muddy beaches, often projecting from the sand .[1]

Typically found in the intertidal zone at the water's edge at a mean distance from sea level of 59.00 meters (193.57 feet).[2]

Biome: Coastal.
